Front

What is the formula to calculate distance when speed and time are known?

Back

Distance = Speed × Time

Front

If Martin can travel 174 miles in 3 hours, what is his speed in miles per hour?

Back

Speed = Distance / Time = 174 miles / 3 hours = 58 miles per hour

Front

How do you convert miles per hour to feet per second?

Back

Multiply the speed in miles per hour by 1.46667 to convert to feet per second.

Front

What is the speed of a fox in feet per second if it runs at 42 miles per hour?
