11-47.

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.
