Quick revision
Remember these!
- Speed = Distance ÷ Time.
- 120 km in 2 hours = 60 km/h speed.
- Speed is measured in km/h for vehicles.
- Speed can be measured in m/s for shorter movements.
- Comparing speeds shows which is faster.
- An 80 km/h train is faster than a 60 km/h car.
- Basic speed calculations use distance and time.
- This skill helps interpret travel information.
