Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes eac
h day. He ran 2 miles around the football field before school and ran a longer route through his neighborhood after school. By the end of the week, Russell had run a total of 30 miles. Which equation can Russell use to find how many miles, x, he ran each day after school?
Alexander has to miles to go because if one mile is a third you can simply maltiply by three, then subtract the mile he already went. you maltiply by three because it was a third of the way there
