Activity • The bus is at Point A on the map and we are at Point G. We want to help the engineers figure out how long it will be until the next bus arrives. • Brainstorm missing factors needed to determine how long it will take for the next bus to arrive

Closure • What is an engineer? • What kinds of things do engineers do? • How can engineers determine when the next bus will arrive?
