11-47.

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 ✎

Write equations for how long it took for Mimi and Marisol to walk to the shopping mall, where x = the time in hours.

Look back at problem 11-24, which is a similar problem.

Set the equations equal to each other and solve for x.

Substitute the value for x that you found into one of the original equations you wrote to find how far the school is from the mall.
