- A. 42 km/h
- B. 45 km/h
- C. 48 km/h (Correct)
- D. 50 km/h
Explanation: Speed = distance/time = 240/5 = 48 km/h.
- Distance
2. A bike moves at 60 km/h for 2.5 hours. Distance covered is:
- A. 120 km
- B. 130 km
- C. 140 km
- D. 150 km (Correct)
Explanation: Distance = 60 x 2.5 = 150 km.
- Time
3. Time taken to cover 144 km at 36 km/h is:
- A. 3 hours
- B. 4 hours (Correct)
- C. 5 hours
- D. 6 hours
Explanation: Time = 144/36 = 4 hours.
- Train
4. A 150 m train passes a pole in 10 seconds. Speed is:
- A. 12 m/s
- B. 15 m/s (Correct)
- C. 18 m/s
- D. 20 m/s
Explanation: Speed = 150/10 = 15 m/s.
- Relative Speed
5. Two trains move in opposite directions at 55 km/h and 65 km/h. Relative speed is:
- A. 100
- B. 110
- C. 120 (Correct)
- D. 130
Explanation: Opposite direction speeds add up.
- Boats
6. Boat speed in still water is 20 km/h and stream speed is 4 km/h. Downstream speed is:
- A. 14
- B. 16
- C. 20
- D. 24 (Correct)
Explanation: Downstream speed = 20 + 4.
- Boats
7. Boat speed in still water is 20 km/h and stream speed is 4 km/h. Upstream speed is:
- A. 14
- B. 16 (Correct)
- C. 18
- D. 24
Explanation: Upstream speed = 20 - 4.
- Average Speed
8. A person goes from town A to B at 30 km/h and returns at 20 km/h. Average speed for the whole trip is:
- A. 22
- B. 24 (Correct)
- C. 25
- D. 26
Explanation: Average speed = 2ab/(a+b) = 2 x 30 x 20 / 50 = 24.
- Meeting Problem
9. Two people start 180 km apart and move towards each other at 40 km/h and 50 km/h. They meet after:
- A. 1.5 hr
- B. 2 hr (Correct)
- C. 2.5 hr
- D. 3 hr
Explanation: Relative speed = 90 km/h, so time = 180/90 = 2 hours.
- Trains
10. A 120 m train crosses a 180 m platform in 15 seconds. Speed is:
- A. 15 m/s
- B. 18 m/s
- C. 20 m/s (Correct)
- D. 24 m/s
Explanation: Total distance = 300 m, so speed = 300/15 = 20 m/s.
- Speed Change
11. If speed is increased by 25%, time for the same journey decreases by:
- A. 15%
- B. 20% (Correct)
- C. 25%
- D. 30%
Explanation: New time factor = 1/1.25 = 0.8, so time decreases by 20%.
- Train Crossing
12. A 180 m train moving at 54 km/h crosses a standing man in:
- A. 10 sec
- B. 12 sec (Correct)
- C. 15 sec
- D. 18 sec
Explanation: 54 km/h = 15 m/s, so time = 180/15 = 12 sec.
