### M. Henke in Mr. Kirkland's Math II Class

Problem:

A surveyor needs to measure the distance, MN, across the lake. Beginning at Q, he locates the midpoint, O, of MQ and the midpoint, P, of NQ. He then measures OP. What is MN?

To answer this word problem I use a brace map with diagrams to help me solve step by step and organize information.

The measure of MN will be 92m.
