Look at the map and list of facts below. Can you figure out the distances in miles between the cities? Can you name the cities using the facts? In this concept we will learn how to read and work with maps.

Facts:

  1. Woodstock to Toledo is 40 miles.
  2. Mesa to Kent is 80 miles.
  3. Rocky Creek to Mesa round trip is 40 miles.
  4. Mesa to Toledo is the same distance as Woodstock to Kent.

Guidance

In order to solve the problem above, use the problem solving steps.

  • Start by describing what information is given.
  • Then, identify what your job is. In these problems, your job will be to figure out where each city is on the map.
  • Next, make a plan for how you will solve. In these problems, measure distances with a ruler and use the facts to figure out which city is which.
  • Then, solve the problem.
  • Finally, check your solution. Verify that the measured distances between the cities work with the facts.

Example A

Use your ruler and the key. Figure out distances in miles between cities. Then use the facts to name the cities.

Facts:

  1. Bakersville to Zucker is 100 miles.
  2. Zucker to Saugus is 75 miles.
  3. Saugus is halfway between Bakersville and Dayton.
  4. Akron is 50 miles from Saugus.
