6th grade Q3

Let's see how you can use the speed, distance, time triangle to calculate speed, distance, and time.

Before you start, remember this: If the speed is given in kilometers per hour (km/h), then the time should be in hours (h) and the distance in kilometers (km). If they're not, you'll need to change them so they match!

Example 1. Finding Time
Problem: A cyclist is traveling at a speed of 20 km/h. How long will it take to travel a distance of 80 kilometers?
Explanation: To find time, cover the 'T' in your triangle. You will see that distance divided by speed gives you time.

Example 2. Finding Distance
Problem: A car travels for 5 hours at a speed of 60 km/h. How far does the car go?
Explanation: To find distance, cover the 'D' in your triangle. The formula shown is speed multiplied by time.

Example 3. Finding Speed
Problem: A runner takes 2 hours to cover a distance of 10 kilometers. What was the runner's speed?
Explanation: To find speed, cover the 'S' in your triangle. The operation needed is distance divided by time.

Now you know how the speed, distance, and time triangle can help you solve problems quickly and easily.
