Convert 72 km/h to m/s.
- 15 m/s
- 20 m/s
- 25 m/s
- 30 m/s
Show answer and solution
Correct answer: B. 20 m/s
1. m/s = km/h × 5/18.
2. 72 × 5/18.
3. = 20 m/s.

A train 120 m long passes a pole in 6 seconds. What is its speed in km/h?
- 60
- 72
- 80
- 90
Show answer and solution
Correct answer: B. 72
1. Speed (m/s) = 120 / 6 = 20 m/s.
2. To km/h: 20 × 18/5.
3. = 72 km/h.
