Question

Russell has been training for the Emerald Valley Race. The first week he trained, he ran 5 days and took the same two routes each 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?

Answer 1

Answer:the equation would be something like 30=5x+10

Step-by-step explanation:we know the total is 30 miles

he ran 5 days

the morning run is 2 miles

2*5=10

10 plus the unknown miles times 5 days gives us 30

so 30=5x+10 subtract 10 both sides

20= 5x=20

divide both sides by 5

x=4

Answer 2

Answer:

x=4

Step-by-step explanation:

5day, 2m before school, total 10m before school

5x after school

10+5x=30

5x=30-10

5x=20

x=4
