Question

. On a recent business trip, a salesman traveled 52 miles the first hour, 64 miles the second hour and 49 miles the third hour. How many miles did he average per hour? Type your answer in the box. _____ miles per hour.

Answer 1

Remark

The average is found by adding the total miles and dividing by the total number of hours.

Average

total distance = 52 + 64 + 49

Total distance = 165 miles

Total time = 1 + 1 + 1 = 3 hours.

Average = total distance/ total time

Average = 165  /   3 = 55 miles per hour.
