A cyclist rides his bike at a speed of 27 miles per hour. What is this speed in feet per second

Answer 1

You need to convert miles to feet and hour to seconds.

There are 5280 feet in 1 mile, and 3600 seconds in 1 hour.

So the cyclist will ride 142,560 feet (5280 x 27) in 3600 seconds (60 seconds x 60 minutes x 1 hour)

Divide this to get the final answer of 39.6 Feet per Second (142,560 / 3600)

Hope this helps.
