Evan is training for a race on Saturday. He wants to run a total of 12 miles total for the week before the race. On Monday he ran 3 miles, on Tuesday he ran 5 miles, he took Wednesday and Friday off. How many miles does he need to run on Thursday to meet his goal? A) 0 miles- he has already met his goal. B) 1.5 miles C) 2 miles D) 4 miles
In order to find this, lets work it.
This means that our equation will look like:
5+3+x=12
Lets combine like terms.
8+x=12.
We now must subtract 8 from both sides.
x=4.
This means Evan will need to run 4 miles on Thursday to meet his goal.
Your answer is: D) 4 miles
