5280 ft = 1 mile
3600 sec = 1 hour
78 mph = (78 x 5280) / 3600 ft/sec = 114.4 ft/sec

78 X 5280 / 3600 = 114.4 ft/s
1 mile is 1760 yards or 5280 feet and 1 hour is 3600 seconds. Multiply the numerator to get feet and divide by 3600 to get per second.

60 miles per hour is exactly 88 feet per second. Setting up a proportion,
x/78 = 88/60
x = 78*88/60 = 114.4 fps

Unit analysis:
( 78 miles / hour ) x ( 1 hour / 60 min ) x ( 1 min / 60 sec ) x ( 5280 feet / 1 mile) = ( 114.4 feet / sec )

5280> ft per mile
78> mph
60> minutes per hour
60>seconds per minute
5280*(multiply)78=411840
411840/(devide)60=6864
6864/(devide)60=114.4
The answer is <114.4 FPS>
