Question: 1 / 400

A salesman traveled 52 miles, 64 miles, and 49 miles over three hours. What is his average speed per hour?

49 miles/hour

52 miles/hour

55 miles/hour

To find the average speed of the salesman, we first need to calculate the total distance traveled and the total time spent traveling.

The salesman traveled distances of 52 miles, 64 miles, and 49 miles. Adding these distances together gives us:

52 miles + 64 miles + 49 miles = 165 miles.

Next, we note that the total time spent traveling is 3 hours.

The average speed is calculated using the formula:

Average speed = Total distance ÷ Total time.

Substituting the values we have:

Average speed = 165 miles ÷ 3 hours = 55 miles/hour.

This average speed represents the overall speed at which the salesman was traveling over the total distance covered in the total time. Thus, the correct answer, which indicates the average speed per hour, is indeed 55 miles/hour.
