Question

khalil took a train from San Francisco to San Jose, which is a distance of 54 miles. The train took 45 minutes for the trip. What was the average speed of the train expressed in miles per hour?

Answer 1

To find the average speed in miles per hour, you will create a rate using the number of miles to the number of hours in 45 minutes.

54 miles in 0.75 hours (45 minutes)

To make this a unit rate or miles per hour, divide the number of miles by the time.

54/0.75 = 72 mph

The train traveled an average speed of 72 mph.
