Lesson 8

Scale Drawings and Maps

Let’s use scale drawings to solve problems.

8.1: A Train and a Car

Two cities are 243 miles apart.

  • It takes a train 4 hours to travel between the two cities at a constant speed.

  • A car travels between the two cities at a constant speed of 65 miles per hour.

Which is traveling faster, the car or the train? Be prepared to explain your reasoning.

8.2: Driving on I-90

  1. A driver is traveling at a constant speed on Interstate 90 outside of Chicago. If she traveled from Point A to Point B in 8 minutes, did she obey the speed limit of 55 miles per hour? Explain your reasoning.
