Question

Charlene is training for a marathon. She runs 5 miles per day for 5 days each week. If M stands for the total number of miles she runs and W stands for the number of weeks she trains, which equation can be used to find the number of kilometers she has run?

A.
W = 25M

B.
M = 25W

C.
W = 5M
