Lesson 3: Rate Problems—Imperial and Metric Systems

 

Focus

 

Have you ever accomplished a goal that you thought was impossible? Imagine climbing a mountain. Now imagine climbing a mountain in a wheelchair! Many people, including Canadian Jim Milina (shown in the photo on the right), have climbed mountains in wheelchairs.

 

Mount Kilimanjaro is a mountain in Tanzania that Jim Milina climbed in his customized wheelchair with the help of friends and local guides. What reasons can you think of for using a special wheelchair for Jim’s climb?

 

Mount Kilimanjaro is 5895 m high from sea level to the summit. It is the highest point on the African continent.

 

Try this question to imagine just how tall this mountain is: If you were standing on each others' shoulders, how many people of the same height as you would it take to be as tall as Mount Kilimanjaro?

How long do you think it would take to climb Mt. Kilimanjaro? If you knew how long this journey would take, you could then make daily plans for

• how many kilometres you would climb
• how long of a rest you would take
• how much food and water you would need

Lesson Question

• How are tables used to solve rate problems that move between metric and imperial systems?
