If a car travels 60 miles in 1.5 hours, what is its average speed in miles per hour?

To determine the average speed of the car, you can use the formula for speed, which is distance divided by time. In this case, the car travels a distance of 60 miles in a time of 1.5 hours.

First, you divide the total distance by the total time:

Average speed = Total distance / Total time
Average speed = 60 miles / 1.5 hours = 40 miles per hour.

This calculation shows that the average speed of the car is 40 mph. Recognizing how to use this formula is essential for solving similar problems involving distance, speed, and time. The choice of 40 mph clearly reflects the correct computation based on the given distance and time.
