Mastering Speed, Distance, and Time
Learning Objective
At the end of the lesson you will confidently solve problems using the relationship between speed, distance and time, and explain how these concepts connect.
What is Speed?
Speed tells us how fast something is moving.
The Speed Formula
Speed = Distance /Time.
Standard units:
Distance: metre (m),
Time: seconds (s), and
Speed: metre per second (m/s).
Changing the Formula
Distance = Speed x Time
Time = Distance/ Speed
You can rearrange the formula to find distance or time if you know the other values.
Standard Units Explained
Measured in seconds (s). Sometimes given in minutes or hours.
Measured in metres (m). Can also be measured in kilometres (km)
Distance
Time
Practice: Quick Questions
1. An airplane travels at 500 mph. How far will it go in 2 hours? 2. An athlete runs at 10 m/s. How long for 200 m? 3. A football at 10 m/s- how far in 8 seconds? Show your working for each.
Key Takeaways
Speed, distance and time are closely linked. Use the formulae to solve practical problems, and always check your units.
