If a car travels 180 miles in 3 hours, what is its average speed in mph?

To determine the average speed of the car, you can use the formula for average speed, which is calculated by dividing the total distance traveled by the total time taken. In this case, the car travels a distance of 180 miles over a time span of 3 hours.

The calculation would proceed as follows:

Average Speed = Total Distance / Total Time

Average Speed = 180 miles / 3 hours = 60 miles per hour (mph)

This result indicates that the car’s average speed is 60 mph, which aligns with the first choice. This calculation correctly applies the definition of average speed and reflects an understanding of distance and time relationships in a straightforward manner.
