valeria has been training for the charlestown cruisers bike race. the first week she trained, she rode 5 days and took the same two routes each day. she rode an 8 - mile route each morning and a longer route each evening. by the end of the week, she had ridden a total of 115 miles. how many miles did valeria ride each evening? write your answer as a whole number or a decimal.
Answer
Explanation:
Step1: Calculate morning - ride distance per week
She rode 5 days, 8 - mile route each morning. So the total morning - ride distance per week is $5\times8 = 40$ miles.
Step2: Calculate total evening - ride distance per week
The total distance she rode in a week is 115 miles. Subtract the total morning - ride distance from the total weekly distance. So the total evening - ride distance per week is $115−40=75$ miles.
Step3: Calculate evening - ride distance per day
She rode 5 days. Divide the total evening - ride distance per week by 5. So the distance she rode each evening is $\frac{75}{5}=15$ miles.
