Question

Robert is training for a half-marathon. On Saturday, he ran 3 miles in 34.5 minutes. What is his unit rate in miles per hour (mph)? (Round to the nearest tenth.)

Answers

  1. Robert’s unit rate in miles per hour (mph) is 5.2 miles per hour.

    What is speed?

    Speed is the change in displacement resulting from the interaction of distance with time.
    Speed measures the ratio of distance to time.

    Data and Calculations:

    Distance covered in 3 miles = 34.5 minutes
    Distance to be covered in one hour = 5.217 miles (3/34.5 x 60)
    Robert’s speed = 5.2 miles per hour.
    Thus, Robert’s unit rate in miles per hour (mph) is 5.2 miles per hour.
