what is a knotical mile versus a mile per hour?
962871
One nautical mile (at sea) is 6076 feet.  A land mile is 5280 feet.  A knot is one nautical mile per hour, or 6086/5280 = 1.15 mi/hr.  The expression comes from the olden days practice of using a rope with knots every 6076 feet to measure speed at sea.  A buoy would be put in the water off the stern of the boat, and the rope paid out and timed.  When the knot passted over the stern, that was one nautical mile, and the speed could then be calculated using the time.

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.

A mile is a linear measurement (length) while 1000 sq. ft. would be a two dimensional measurement (length x width) so it's pretty hard to compare the two.\n\nYou can compare 1000 sq. ft. to a square mile, which is 27,878,400 sq. ft. so it is approximately 0.0036% of a square mile.

An acre is a 2D measurement, and a mile is 1D. You can't compare them.

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) )

A: 56 mph x 1.5 hours = 84 miles\n\n\nB: Distance = 100 total miles - 84 miles = 16 miles.\nTime = 30 minutes = 0.5 hours.\n\nAverage speed = 16 miles / 0.5 hours = 32 miles per hour.\n\n\nC: Total trip miles = 100 miles\nTotal time = 2 hours (1 hour 30 minutes for first leg, 30 minutes for final leg)\n\nAverage speed = 100 miles / 2 hours = 50 miles per hour.

5.5 miles per hour is about 11 minutes per mile. This is not really fast, but it isn't a bad start. I like to be about 8 miles per hour. The elite runners are about 15 miles per hour for 1 mile.
