This Application Problem is a part of the Lesson 22, Unit 7, Grade 2. Liza, Cecilia, and Dylan are playing soccer. Liza and Cecilia are 120 feet apart. Dylan is in between them. If Dylan is standing the same distance from both girls, how many feet is Dylan from Liza? In this problem, students synthesize their understanding of length by finding the middle point on a number line and realizing that the length from 0 to 60 feet is equal to the length from 60 to 120 feet.
