Q1. The speedometer of a car reads 54 km/h on a straight road. Expressed in SI units, what is this speed in m/s?
- A.27 m/s
- B.5.4 m/s
- C.15 m/s
- D.194.4 m/s
Answer: C. 15 m/s
To convert km/h to m/s multiply by 5/18. So 54 km/h = 54 * 5/18 = 15 m/s.
Q2. A bus maintains 72 km/h along a highway. Converting to metres per second, what value do you get?
- A.36 m/s
- B.20 m/s
- C.7.2 m/s
- D.259.2 m/s
Answer: B. 20 m/s
To convert km/h to m/s multiply by 5/18. So 72 km/h = 72 * 5/18 = 20 m/s.
Q3. During a steady run a train clocks 36 km/h. What is the equivalent speed in m/s?
- A.3.6 m/s
- B.129.6 m/s
- C.18 m/s
- D.10 m/s
Answer: D. 10 m/s
To convert km/h to m/s multiply by 5/18. So 36 km/h = 36 * 5/18 = 10 m/s.
