Question

Convert 50 feet per second to miles per hour.

Answer 1

FIrst we know that
1  second = 1/3600 hours
5280 ft = 1 miles

Which means that

50 Ft = 50/5280 miles




So the conversion 
(5/5280 miles ) / (1/3600)

= 5/5280 miles x 3600

= 34.09 miles per hour

Answer 2

60*60=3600
3600*50=180,000
180,000/5280=34.09
34.09 mph.
