Divide the distance traveled over the time to find the constant speed.
Divide the distance traveled over the time to find the constant speed.
Determine the constant speed in miles per hour by multiplying miles per minute by 60. For the example, 2 x 60 = 120 miles per hour for the constant speed of the race car in the example.
Practice with an example of a race car which travels 20 miles in 10 minutes. Divide 20/10 to find a constant speed of 2 miles per minute.
