1. Pick a large city in Southern, Eastern, or Central Washington that you have never been to: . 2. Use the edge of a piece of paper to mark the 50 mile distance as shown on the scale. Call this 1 "unit." Then estimate how many "units" between Shoreline and the city you choose in #1.

# of units:

3. Convert the "units" to miles.

4. If you drove at an average speed of 55 mph, how long would it take you to get there?

5. Suppose your car gets 30 miles per gallon and holds 13 gallons. How much gas will you need for the round trip?

6. If gas costs about $3.50 pr gallon, how much will the gas for the trip cost?

7. Now look up the actual driving distance and time between Shoreline and your city on Google Maps. How close were your calculations?
