Learning Intention: Solve straight forward problems based on speed, time and distance
Diagnostic:
What is the average speed of a car that travels 100 km in 2 hours?
What is the average speed of a cyclist who travels 60 km in 3 hours?
What is the average speed of a runner that travelled 3000 m in 6 minutes?
Explanation:
Speed: how far an object travels in a certain amount of time.
Speed is calculated by dividing the distance travelled by the time taken.
This formula triangle allows you calculate either speed or distance or time if you have any two out of the three.
Example:
What is the average speed of a car that travels 120 km in 2 hours?
Speed = distance ÷ time
Speed of car = 120 km ÷ 2 hours
Speed of car = 60 km / hr
