how do i figure out how to change mph to feet meters and inches per second?

Question

for example if a car goes 40 mph how do i figure out how to get that in ft,meters,and inches per second

Answer 1

40 miles per hour is 40*5280 feet per hour. Divide that by 3600 (seconds per hour) to get feet per second. Apply the other conversion factors (1 meter = 3.28084 ft.
12 in = 1 ft, etc.) to get the other answers.
