Austin walks to school every day. If (m) represents the number of miles that Austin walks one way, which of the following represents how many miles he walks in a round trip from his house to school and back?
a. 2 + m
b. 2m
c. 2-m
d. 2/m
Answer: b
Explanation:
This is a word problem that is asking us to find the total miles walked in a round trip. The term round-trip means that Austin will have done the trip twice, once from his house to the school and back from the school to his house. Twice anything means two times the thing that is asked. In this case we are asked for miles so for the round trip the answer will be 2m.
