A cheetah ran 300 feet in 2.92 seconds. What was the cheetahs average speed in miles per hour?

There are 3600 seconds in an hour (60 minutes times 60 seconds)

If the cheetah ran 300 ft in 2.92 seconds that would mean he ran 102.74 feet per second (300/2.92) Multiply the 102.74 by 3600 seconds to come up with 369864 feet an hour.

We know from the information on this site that there are 5280 feet in a mile so now we need to solve 369864/5280. The solution is 70.05 miles.

The cheetah ran an average of 70.05 miles an hour.
