Answer
Explanation:
Step1: Calculate morning - ride total
She rode 5 days and 8 miles each morning. So the total miles she rode in the morning is $5\times8 = 40$ miles.
Step2: Calculate evening - ride total
The total miles she rode in a week is 115 miles. Subtract the morning - ride total from the weekly total to get the total miles she rode in the evening. That is $115−40=75$ miles.
Step3: Calculate miles per evening
She rode 5 days in the evening. Divide the total evening - ride miles by 5 to find out how many miles she rode each evening. So, $\frac{75}{5}=15$ miles.
