- Speed
1. A bike covers 150 km in 3 hours. Its speed is:
- A. 40 km/h
- B. 45 km/h
- C. 50 km/h (Correct)
- D. 55 km/h
Explanation: Speed = 150/3 = 50 km/h.
- Distance
2. A bus moves at 48 km/h for 5 hours. Distance covered is:
- A. 220 km
- B. 230 km
- C. 240 km (Correct)
- D. 250 km
Explanation: Distance = speed x time = 48 x 5.
- Time
3. Time taken to cover 90 km at 30 km/h is:
- A. 2 hr
- B. 3 hr (Correct)
- C. 4 hr
- D. 5 hr
Explanation: Time = distance/speed = 90/30 = 3 hours.
- Train
4. A 180 m train passes a pole in 12 seconds. Its speed is:
- A. 12 m/s
- B. 15 m/s (Correct)
- C. 18 m/s
- D. 20 m/s
Explanation: Speed = 180/12 = 15 m/s.
- Relative Speed
5. Two trains move in opposite directions at 55 km/h and 35 km/h. Relative speed is:
- A. 20
- B. 55
- C. 70
- D. 90 (Correct)
Explanation: Opposite directions means speeds add.
- Relative Speed
6. Two trains move in the same direction at 72 km/h and 54 km/h. Relative speed is:
- A. 12
- B. 15
- C. 18 (Correct)
- D. 24
Explanation: Same direction means difference of speeds.
- Boats
7. Boat speed in still water is 15 km/h and stream speed is 4 km/h. Upstream speed is:
- A. 9
- B. 10
- C. 11 (Correct)
- D. 12
Explanation: Upstream speed = 15 - 4.
- Boats
8. Boat speed in still water is 15 km/h and stream speed is 4 km/h. Downstream speed is:
- A. 17
- B. 18
- C. 19 (Correct)
- D. 20
Explanation: Downstream speed = 15 + 4.
- Average Speed
9. A man goes at 40 km/h and returns at 60 km/h. Average speed is:
- A. 46 km/h
- B. 48 km/h (Correct)
- C. 50 km/h
- D. 52 km/h
Explanation: Average speed = 2ab/(a+b) = 2 x 40 x 60 / 100 = 48.
- Unit Conversion
10. 54 km/h is equal to:
- A. 12 m/s
- B. 15 m/s (Correct)
- C. 18 m/s
- D. 20 m/s
Explanation: Multiply by 5/18: 54 x 5/18 = 15.
- Unit Conversion
11. 20 m/s is equal to:
- A. 60 km/h
- B. 72 km/h (Correct)
- C. 80 km/h
- D. 90 km/h
Explanation: Multiply by 18/5: 20 x 18/5 = 72.
- Meeting Problems
12. Two persons 210 km apart move towards each other at 60 km/h and 45 km/h. They meet after:
- A. 1 hr
- B. 2 hr (Correct)
- C. 2.5 hr
- D. 3 hr
Explanation: Relative speed = 105 km/h, time = 210/105 = 2 hours.
- Trains
13. A 250 m train crosses a 350 m platform in 30 seconds. Speed is:
- A. 18 m/s
- B. 20 m/s (Correct)
- C. 22 m/s
- D. 25 m/s
Explanation: Total distance = 600 m, speed = 600/30 = 20 m/s.
- Speed Change
14. If speed increases by 20%, the time for the same distance decreases by:
- A. 16 2/3% (Correct)
- B. 18%
- C. 20%
- D. 25%
Explanation: New time factor = 1/1.2 = 5/6, so decrease = 1/6 = 16 2/3%.
- Train Crossing
15. A 150 m train moving at 45 km/h crosses a man walking at 9 km/h in the opposite direction. Time taken is:
- A. 8 sec
- B. 9 sec
- C. 10 sec (Correct)
- D. 12 sec
Explanation: Relative speed = 54 km/h = 15 m/s, time = 150/15 = 10 sec.
