25 mi/h ≈ ft/s and round to the nearst tenth

Answer 1

25 mi/hr x 5,280 ft/1 mile x 1 hr/60 min x 60 min/1 hour = 36.7 ft/sec

Another method: We know if you are going 60 mi/hr, you are going a mile per minute or 5,280 ft per 60 seconds

So, using a ratio, (x ft/sec)/(25 mi/hr) = (5,280 ft/60 seconds)/(60 miles/hr) =

or x = (25)(5,280)/60 = 36.7 ft/sec
