Problem 1: Sidek travels 450 km in 5 hours. What was his speed in km/h?
We know:
- Distance = 450 km
- Time = 5 hours
Formula for speed:
Speed = Distance ÷ Time
So, plug in the numbers:
Speed = 450 ÷ 5
Do the division:
450 ÷ 5 = 90
✔ So, Sidek’s speed is
90 km/h

Problem 2: Munirah runs 200m in 25 seconds. What is her speed in m/s?
We know:
- Distance = 200 meters
- Time = 25 seconds
Formula:
Speed = Distance ÷ Time
Plug in the numbers:
Speed = 200 ÷ 25
Do the division:
200 ÷ 25 = 8
✔ So, Munirah’s speed is
8 m/s

Problem 3: A shuttlecock travels 750 cm in 3 seconds. What is the speed of the shuttlecock in cm/s?
We know:
- Distance = 750 cm
- Time = 3 seconds
Formula:
Speed = Distance ÷ Time
Plug in the numbers:
Speed = 750 ÷ 3
Do the division:
750 ÷ 3 = 250
✔ So, the shuttlecock’s speed is
250 cm/s

Final Answer:
1. 90 km/h
2. 8 m/s
3. 250 cm/s
