10-85.

**10-85. **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* = 2*t*

Mimi: *d* = 3(*t* − 1)

*t* = 3 hours

Note: The question asks how far the mall is from their school.
