Question

The approximate length of a

marathon race is 26 miles. The
approximate length of a half-
marathon race is 13 miles. Last
year, a runner ran 1 marathon
and 3 half-marathons. Which
expression represents the total
number of miles the runner ran in
these races?
a. (26 + 1) x (13 + 3)
b. (26 x 1) + (13 x 3)
c. (26 + 13) x (1 + 3)
d. (26 x 13) + (1 x 3)

Answer 1

The answer is letter B

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.
