- Speed
1. A car travels 120 km in 3 hours. Its speed is:
- A. 30 km/h
- B. 40 km/h (Correct)
- C. 45 km/h
- D. 60 km/h
Explanation: Speed = distance/time = 120/3 = 40 km/h.
- Distance
2. A train moving at 60 km/h covers what distance in 2 hours?
- A. 100 km
- B. 110 km
- C. 120 km (Correct)
- D. 140 km
Explanation: Distance = speed × time = 60 × 2 = 120 km.
- Time
3. If a man runs at 12 km/h, the time taken to cover 36 km is:
- A. 2 hr
- B. 3 hr (Correct)
- C. 4 hr
- D. 5 hr
Explanation: Time = distance/speed = 36/12 = 3 hours.
- Train
4. A 150 m train passes a pole in 10 seconds. Its speed is:
- A. 10 m/s
- B. 12 m/s
- C. 15 m/s (Correct)
- D. 18 m/s
Explanation: Speed = 150/10 = 15 m/s.
- Train
5. A 200 m train crosses a platform 300 m long in 25 seconds. Speed is:
- A. 18 m/s
- B. 20 m/s (Correct)
- C. 22 m/s
- D. 25 m/s
Explanation: Total distance = 200 + 300 = 500 m, speed = 500/25 = 20 m/s.
- Boats and Streams
6. Boat speed in still water is 12 km/h and stream speed is 3 km/h. Downstream speed is:
- A. 9
- B. 12
- C. 15 (Correct)
- D. 18
Explanation: Downstream speed = 12 + 3 = 15 km/h.
- Boats and Streams
7. With still water speed 12 km/h and stream speed 3 km/h, upstream speed is:
- A. 6
- B. 8
- C. 9 (Correct)
- D. 10
Explanation: Upstream speed = 12 - 3 = 9 km/h.
- Average Speed
8. A person travels from A to B at 30 km/h and returns at 20 km/h. Average speed for the whole journey is:
- A. 24 km/h (Correct)
- B. 25 km/h
- C. 26 km/h
- D. 27 km/h
Explanation: Average speed = 2ab/(a+b) = 2×30×20/50 = 24.
- Relative Speed
9. Two trains move in opposite directions at 40 km/h and 50 km/h. Relative speed is:
- A. 10
- B. 40
- C. 50
- D. 90 (Correct)
Explanation: Opposite directions means speeds add.
- Relative Speed
10. Two trains move in same direction at 60 km/h and 45 km/h. Relative speed is:
- A. 10
- B. 15 (Correct)
- C. 20
- D. 25
Explanation: Same direction means difference of speeds.
- Unit Conversion
11. 72 km/h is equal to:
- A. 18 m/s
- B. 20 m/s (Correct)
- C. 22 m/s
- D. 24 m/s
Explanation: Multiply by 5/18: 72 × 5/18 = 20 m/s.
- Unit Conversion
12. 15 m/s is equal to:
- A. 36 km/h
- B. 45 km/h
- C. 54 km/h (Correct)
- D. 60 km/h
Explanation: Multiply by 18/5: 15 × 18/5 = 54 km/h.
- Meeting Time
13. Two persons are 180 km apart and move towards each other at 50 km/h and 40 km/h. They meet after:
- A. 1 hr
- B. 2 hr (Correct)
- C. 3 hr
- D. 4 hr
Explanation: Relative speed = 90 km/h, so time = 180/90 = 2 hours.
- Speed-Distance
14. If speed increases by 25%, time taken to cover a fixed distance decreases by:
- A. 10%
- B. 15%
- C. 20% (Correct)
- D. 25%
Explanation: New time factor = 1/1.25 = 0.8, so time decreases by 20%.
- Train Crossing
15. A 120 m train moving at 54 km/h crosses a man walking in opposite direction at 6 km/h in:
- A. 6 sec
- B. 7 sec (Correct)
- C. 8 sec
- D. 9 sec
Explanation: Relative speed = 60 km/h = 50/3 m/s. Time = 120 ÷ (50/3) = 7.2 sec, so nearest is 7 sec.
