An introduction to the difference between distance traveled and displacement.

Using a one-dimensional number line to visualise and calculate distance and displacement.

This video introduces you to the concept of ratios.

Managing time involves accurately predicting how much time it will take to do a task, and then setting aside that amount of time to complete it. Managing time is much more difficult than it may seem, which is why there are entire courses of study and research on the best approaches. But if you develop a method to undertake each component, you’ll be successful.

Using position-time graphs and number lines to find displacement and distance traveled.

This YouTube video can help to get deeper understanding on solving ratio and proportion problems.

Outcomes

In this course you will learn about:

1. Ratio and rate.
2. Direct and indirect proportion.
3. Simple interest.
