how may laps in a 25 yard pool equals a mile?
819824
A 25 yards pool, it will take 35.2 laps.  Thats considering 50 yards equals one lap.  \nIf you consider 25 yards is equal one lap then it would be 70.4 laps.\n25 yards x 70.4 laps = 1760 yards\n25 yards x 3 feet x 70.4 laps = 5280 feet\n1 mile = 1760 yards or 5280 feet

well, i'm only familiar with american swimming so i will give you that:\n\nthe longest distance swam period i don't know.  i would imagine someone at some point attempted to swim across an ocean.  depending on how far they got, that would most likely be the record, but as far as organized timed swims are concerned, there is an american record for a distance of 26 miles-385 yards\n\nchad fallin...13:10.28.00 and robin boughey...14:07.27.90

The oval tracks around football fields are usually 440 yards in length. One yard = 3 feet and one lap around the track equals 1,320 feet.

Swimming a mile per hour would burn the same 453 calories as running a 12 minute mile. Amazingly if you are running a 8 minute mile you would burn 708 calories. That's if you are 125 lb.

now and still 50 m olympic (long course 4 laps) size but someplace have small space so they made it 25 m (short course 8 laps)

1 mile=5280ft\n1 meter=3.28ft\n50m=164ft\n5280ft/164ft/length=32.2 lengths=16.1laps

12 miles per hour\n\nIf you run 1 mile in 5 minutes means you have to run .2 miles per minute.   (.2 miles per min X 5 min = 1 mile)\n\nIf you run .2 miles per minute for 60 minutes you would have run 12 miles. (.2 mpm X 60 minutes = 12mph)

write the fraction you need \n\nhow many feet in two miles......\nmiles on one side of eq ..... feet on other ....\nso use conversion that has feet in numerator\n2 (miles)  *    (5280 feet) / mile  .......  the miles cancel and you're left with 2 * 5280 feet \n\n\nhow many feet in 6 yards .....  ( conversiion has feet in numerator)\n6 yds  =  (3 feet) / yard   .....  yards cancel and you're left w/ \n6 * 3  feet

People, think about it, the modern world record is 3:40...so anything under 4 minutes is like national champion (of a pretty big country).\n\nA quarter mile is about 8 lengths in a 50 m (olympic size) pool. I'm a certified lifeguard and I think I would be struggling to get under 5:20.\n\nThe average swimmer will definitely take more than 10 minutes.\nThe average lane swimmer will definitely take less than 10 minutes.\n\nAnd 400 m is once around the track (soccer field size) plus the straightaway (100m).

not that good with yards but it depends whether we are talking about man or women / short or long pool.. but the bets times are around 30 sec for 50m... hope it helps

I think almost all tracks are a quarter mile. I've always had to do 4 laps when running the mile.

Let Rover run to E 20 - x metres from R and then swim to P which is the hypotenuse of a right angled triangle with sides x and 5\n\nSo Rover runs (20 - x) m and swims √(x² + 25) m\n\nNow running rate = twice swimming rate.\nSo r = 2s\n\nSo time for running = (20 - x) /r and time for swimming = √(x² + 25)/s\n\nTotal time T = (20 - x) /2s + √(x² + 25)\n= 1/(2s)*(20 - x + 2√(x² + 25)\n\ndT/dx = 1/(2s)*( -1 + 2x/√(x² + 25)) = 0 for stationary points\nie -1 + 2x/√(x² + 25) = 0\nie  √(x² + 25) = 2x\nSquare both sides\nx² + 25 = 4x²\n3x² = 25\nx = ±5/√3\n= ±(5√3)/3 Since x > 0 the negative result is ignored.\nT = 1/2s (20 - (5√3)/3 + 2 √(100/3))\n= 1/2s (20 - (5√3)/3 + 20/√3)\n= 1/2s(20 + 5√3)\n\nIf he swam all the way T = √(425)/s = 5√(17)/s = 10√(17)/2s\nIf he walked to P and then swam straight in T = 20/2s + 5/s\n= 30/2s\n\nSo the quickest time is when he runs [20 - (5√3)/3] m down the beach and swims the rest of the way

Well, the simplest way would be to assume that Alex swims at a constant speed and takes no time at the turnaround.  The resulting graph would be two straight lines - one from the origin to (12, 25) and one from there back to the x-axis (the t-axis) at (24, 0).  You'd need two equations.\n\nFor the first, the slope will be 25/12 (25 yards in twelve seconds), so the equation would be\n\ny = (25/12)x where 0 <= x <= 12\n\n(You can replace the x with t, if you prefer.)\n\nThe other line would have a slope -25/12 (25 yards back in the remaining 12 seconds).  We'll have to use the point/slope form for that one:\n\ny - y1 = m(x - x1)  using m = -25/12 and the point (24, 0)\n\ny - 0 = (-25/12)(x - 24)\n\ny = (-25/12)x + 50\n\nAgain, you can replace x with t.\n\nHope that helps.

First of all, try to get someone to explain to you in person, trainer or soething like that, then make sure that you do any exercise to improve the technique as using a pull or something, then after you are prtty sure you are getting into it, try to do 1/4 of laps more than you use to do, then do 1/2 laps more\n\nWithin a month or two(swimming everyday) You won't have any problem with it and you'll improve your technique and the only matter will be the speed that ypu'll be swimming

The difference in speed is 6.45-5.30 = 1.15 m/s.\n\nThe track is 198 m long - so the faster runner must catch up by this much to lap the slower.\n\nThis will take 198/1.15 seconds.\n\nThe slower one will have run 198 x 5.30/1.15 m.

Here is how I remember this. I used to run track and one event is called the 440. That is a quarter mile and it is 440 yards in a qaurter mile. Multiply that by 4 and you get how many yards in a mile, 1760. Multiply the 1760 by 3 (because there are 3 feet in a yard) and you get how many feet in a mile, 5280.

Stamina comes with practice. If you have a difficult time continuously swimming long distances, break your workout down and do a pyramid or ladder set. Pyramid sets you gradually increase the distance of each set and finish with your longest distanced set. For example, 5 sets of 100, 200, 300, 400 and 500. Ladder sets you increase your distance, then decrease and finish with a short distance. For example, 5 sets of 200, 300, 400, 300 and 200.Increase your distances or the number of sets as you get used accustomed to the sets. Set a goal of how many yards you will like to accomplish in your workout. If you workout for an hour, try to complete 3000 yards, then increase to 3200 and so on.
