60mph(mi/h) to feet per second(ft/s)

Hi there!

There are 5,280 ft in a mile so multiply that by 60

5,280 × 60 = 316,800 ft

There are 60 min in an hour and 60 sec in a minute so multiply 60 sec by 60 sec

60 sec × 60 min = 3600 sec

Now divide 316,800 ft by 3600 sec to get:

316,800 ft ÷ 3600 sec ≈ 88 (ft/s)
