what is 1 mile and 8 mins in mph?

You have miles per minutes, and you want to convert it to miles per hour.  Set it up as fractions so the units cancel out, like this:\n\n1mile/8minutes * 60minutes/1hour  Now the minutes cancel and miles/hour is the final units.  Now just do the math.  60/8 = 7.5 mph.

Average rate per hour = total distance / total time\n=( x + x )/ total time          (1)\nTime required to travel x distance at the speed of 10 miles\nper hour = x / 10 hours.\nTime required to travel x distance at the speed of 8 miles\nper hour = x / 8 hours.\nSo the total time is\n=(x / 10) + (x / 8)\n=18x/80 \n=\nPutiing this value in the denominator of (1)\nWe get\nAverage rate per hour = total distance / total time\n= 2x/[18x/80]\n=80/9\n=8.88\n=8.9 miles/hr\n\n( In general if the speeds are 'a' & 'b', the the average \nis given by their harmonic mean viz. 2*a*b/(a+b) )

Use 1 hour = 3600 seconds, and 1 km = 1000 m.\n\n(18/5) km/hour * (1 hour/ 3600 s) * (1000m/1km)=\nsome number from your calculator.\nPhysical dimension will be meters per second

One mile and 2720 feet.\n\nThere are 5,280 feet in a mile.\nSo, 8000 divided by 5,280 is one mile and 2720 feet.

roughly 11 meters per second, or 24 miles an hour.\n;o)

They ran for 20 mph for 1 minute. In this time, they covered 1/3 of a mile. This means that for the other 9 2/3 miles, they ran at 35 mph.\nThis means their time for that part was 29/105 hours. Add in the 1 minute to get 29/105 + 1/60 to get 41/140 hours as their time. We take 10 divided by this to get their average speed, which is 1400/41 mph, which is approximately 34.14634146 mph.

Distance is found to be the product of velocity and time.  E.G. if you travel at 60 MPH for 2 hours, you travelled (60 M/h) * (2 h).  The hours units cancel giving the answer as 120 miles.\n\nUsing this formula:\nd = v * t\n57 = v * 1.8, so v = 57/1.8 = 31 2/3 FPS.\nTo convert FPS to MPH,\n(31 2/3) * (60*60/5280) = 21.6 MPH.

For a compeletey new starter a good 100 time is 15 sec.200=35 sec. 400=2 min. 18 sec. 800=3 min 11 sec. Mile=7:30.

at four miles per hour for eight hours. 32 miles.

Average speed = (8+8.5)/2=16.5/2 = 8.25 m/s\nTotal distance = 8.25x99=816.75m\nTime taken for 1st Lap = 816.75/(2x8) = 51 sec\nTime taken for 2nd Lap = 816.75/(2x8.5) = 48 sec

The fly has only 1 minute to fly at 60 mph regardless of the back and forth before the trains collide, therefore 1 mile is the distance it will cover.

1 mile = 1.6093 km\nSo 1 km = 1/1.6093 mile\nSo 3 km = 3/1.6093 mile = 1.864165 mile

28 hours..6.5 mph\n\nnot difficult..10 miles the first hour\n                   3 miles the next hour\n\n13 miles in 2 hours therefore 6.5mph\n\n182/6.5=28

Distance = rate x time\n\nif you're going 8 feet per second for 4 seconds, you've gone 32 feet...

D = distance in feet\nt = time in seconds\nS = speed in miles per hour\n\n[D feet x (1 mile/5280 feet)] / [t seconds x (1 hour/3600 seconds)]\n= S miles per hour\n\nDoing the arithmetic, we get:\n0.6818 D / t = S mph\n\nIf D is 150 feet and t is 4 seconds, \n0.6818 (150)/ 4 = 25.56 mph\n\nIf the time is 8 seconds, the speed would be half as much, or \n12.78 mph
