Question

A healthy, adult cheetah can run 110 feet per second. How fast can a cheetah run in miles per hour? Show your work. (1 mile= 5,280 feet) (1 hour = 3600 seconds)

Answer 1

Here is the solution based on the given problem above.
Given: 110 feet/second = speed of the adult cheetah
            ? = speed in miles per hour
Since it is already given that 1 mile = 5280 feet and one hour is 3,600 seconds, let us multiply the values to the given speed.
1 foot = 0.000189394 mile and 1 second = 0.000277778 hour
So 110 feet x  0.000189394 and we get 0.0208333 mile. 
The final answer would be 0.000277778 miles/ 0.000277778 hour.
Hope this answer helps.
