If a car travels 120 miles in 2 hours, what is its average speed?

To find the average speed of the car, we use the formula for average speed, which is total distance divided by total time. In this scenario, the car travels a total distance of 120 miles and takes 2 hours to do so.

Using the formula:

Average Speed = Total Distance / Total Time

Plugging in the given values:

Average Speed = 120 miles / 2 hours = 60 miles per hour (mph)

This calculation shows that the car's average speed is 60 mph, confirming that B is the correct answer.

To summarize the method: you divide the total distance (120 miles) by the total time taken (2 hours) to get the average speed. This concept is essential in understanding how speed is calculated in various scenarios involving distance and time.
