In 2008, Ryan Newman won the Daytona 500 (mile) race with a speed of 152.672 mph. Find his time to the nearest thousandth.

Solution

rate * time = distance.

distance is 500 miles.
rate is 152.672 miles per hour.

substitute in this equation to get:

152.672 * time = 500

divide both sides of this equation by 152.672 to get:

time = 500/152.672 = 3.27499476 hours.

answer should be 3.275 to the nearest thousandth of an hour.
