Question

A car is traveling at 70 ​mi/hour. What is the​ car's speed in feet per​ second?

Answer 1

There are 5,280 feet per mile and
3,600 seconds per hour

70 miles / hour * (5,280 feet / 1 mile) * (1 hour / 3,600 seconds) =
369,600 / 3,600 = 102.666... feet / second
 

Answer 2

70 miles per hour
5280 feet per mile
5280 x 70 = 369600 feet per hour
3600 seconds per hour
369600 divided by 3600 =
102.67 feet per second (rounded to the nearest hundredth)
