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
<h3>How to find the average rate?</h3>
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
