Answer:

The answer is letter B

Step-by-step explanation:

We know obviously when you are multiplying (since it is how MANY he ran that we are multiplying to get total distance), you don't add 1 or 3 to the numbers. We also know he did not run the 26 mile course 13 times, so the only answer choice that is feasible and/or even remotely correct would be B.
