INSTRUCTIONS: Using a ruler measure the distance between each city in the chart. Place your answer in the
column marked 'cm'. Using a calculator or a piece of rough paper multiply each distance In centimetres by 450 (km).
For example: Toronto to Vancouver = 7.4 cm, Distance in km = (7.4 cm) x (450 km) = 3330 km (or 3325 km)
