If you need to be real precise, the first few answers work. In general, mph is two thirds of fps, so 30 fps is 20 mph.

what number feet in 30 miles? that is 30*5280 (definite, we used to apply miles and feet while i grew to become right into a boy!) If the alligator ought to run 158400 feet in an hour (i.e. in 60*60 seconds), what number feet in a million 2d? 158400/3600 = 40 4 so the fee is 40 4 feet in line with 2d. In civilised gadgets, it particularly is 13.4 metre in line with 2d.

There are 3600 seconds in an hour.
30*3600=108000
108,000 ft. in an hour
There are 5,280 ft. in a mile.
108000/5280=(225/11)
(225/11)miles per hour
OR
20.45 miles per hour

20.4545 miles per hour
1ft = 0.00568182 mile
1 second = 0.008333333 hour
hence
30ft/s = 30(0.00568182)/(0.00833333) = 20.4545 miles/hour
