Chapter 3: Ratios and Rates

Hitting The Road

INTRODUCTION

You are going on a road trip with three friends. You can go anywhere in Canada that you can reach by road. You can choose to travel in any vehicle sold in Canada.

 

THE TASK

You will choose a destination and choose how you will drive there, calculate the amount of gas you will need to make the trip, and then calculate how much the gas will cost.

 

THE PROCESS

  1. Choose a destination . You must be able to reach the destination by road. Record your destination, data, and calculations in the Road Sheet.

  2. Determine the distance by road to your destination, in kilometres. (This site works mostly for medium to large towns and cities. You may have to figure out the distance to a nearby town at one end or both ends of your trip. Use a map.)

  3. Choose a vehicle and check out its fuel consumption (L/100 km). (Remember, you have three friends with you!)

  4. Calculate the number of litres of fuel you will use on your trip, using the vehicle you chose. (Use the fuel consumption for highway driving if you will reach the destination mostly by highway.)

  5. Calculate the cost of the gas you will need. You can use local prices, or try Gas Buddy.

  6. Now do the same thing again, to the same destination – only this time, use the most fuel-efficient vehicle you can find. What is the difference in the cost?
