Answer:

He will have to run a total of 8.65 miles to reach his goal.

Step-by-step explanation:

We are given the total of how long he ran for his three short runs, and all we have to do is simplysubtract. We know he has to run 18 miles total, so we subtract the three shorter runs from the total. 18-9.35=8.65. He has to run 8.65 miles in one run, he's going to have a long day.
