Question

On a bicycle, Reshanda rides for 4 hours and is 30 miles from her house. After riding for 11 hours, she is 79 miles away. What is Reshanda's average rate over the last 7 hours of her trip?

Answer 1

Based on the number of miles that Reshanda rode on her bicycle from her house, her average rate over the last 7 hours of the trip was 7 miles per hour

How to find the average rate?

The average rate shows the speed that a person was going over a period of time such that they were able to cover a certain distance, in that period of time.

First, find the number of miles that Reshanda rode in the last 7 hours of her trip on the bicycle:

= Number of miles after 11 hours - Number of miles after 4 hours
= 79 miles - 30 miles

= 49 miles

Reshanda was able to ride for 49 miles in the last 7 hours so her average rate was:

= Distance / Time

= Number of miles ridden / Time ridden

= 49 / 7

= 7 miles per hour
