1. Understanding Speed
Speed is a measure of how fast something is moving. It can be calculated using the formula:
Speed = Distance ÷ Time
2. Calculate the Speed
If a car travels 150 kilometers in 3 hours, what is its average speed? Show your calculation.
3. Real-life Application
You ride your bicycle to a friend's house, which is 12 kilometers away. If it takes you 30 minutes to get there, what was your average speed in kilometers per hour (km/h)? Show your calculation.
4. Convert Speed
Convert the speed you found in Question 3 to meters per second (m/s). Remember that 1 kilometer = 1000 meters and 1 hour = 3600 seconds.
5. Challenge Question
A train travels 240 kilometers in 2 hours and 30 minutes. Calculate the average speed in kilometers per hour. Show your work below.
