10-57.

Mr. Nguyen giving money to his daughters. Marisol and Mimi walked the same distance from their school to a shopping mall. Marisol walked 2 miles per hour, while Mimi left 1 hour later and walked 3 miles per hour. If they reached the mall at the same time, how far from the mall is their school? Homework Help ✎

Since Marisol and Mimi both walked the same distance, write equations for each of their distances.
Be sure to define your variable, t = ...

Let t = amount of time Marisol walked

Marisol: d = 2t
Mimi: d = 3(t − 1)

t = 3 hours
Note: The question asks how far the mall is from their school.
