74.25 feet per second equals mph?

Answer 1

(74.25 ft/sec) * (mile/5280 ft) * (60 sec/min) * (60 min/hr)

You have to set it up with feet in the denominator to cancel feet in the numerator (so divide by 5280 to get miles per second); then seconds in the numerator to cancel the second in the denominator to get miles per minute; then minutes in the numerator to cancel minite in the denominator to get miles per hour. Along with setting up the units of measure, put the appropriate numbers with the units. From there, all you have to do is take 74.25, divide by 5280, multiply by 60, and multiply by 60 again.
