- Speed
1. A car travels 180 km in 4 hours. Its speed is:
- A. 40 km/h
- B. 45 km/h (Correct)
- C. 50 km/h
- D. 55 km/h
Explanation: Speed = distance/time = 180/4 = 45 km/h.
- Distance
2. If a bike moves at 60 km/h for 3 hours, distance covered is:
- A. 160 km
- B. 170 km
- C. 180 km (Correct)
- D. 190 km
Explanation: Distance = speed x time = 60 x 3.
- Time
3. A train runs at 72 km/h. Time taken to cover 144 km is:
- A. 1 hour
- B. 1.5 hours
- C. 2 hours (Correct)
- D. 2.5 hours
Explanation: Time = 144/72 = 2 hours.
- Average Speed
4. A man covers equal distances at 40 km/h and 60 km/h. His average speed is:
- A. 45 km/h
- B. 48 km/h (Correct)
- C. 50 km/h
- D. 52 km/h
Explanation: Average speed for equal distances = 2ab/(a+b) = 48 km/h.
- Train Platform
5. A 150 m train moving at 54 km/h crosses a platform 75 m long in:
- A. 12 s
- B. 15 s (Correct)
- C. 16 s
- D. 18 s
Explanation: Speed = 54 km/h = 15 m/s. Total distance = 150 + 75 = 225 m, so time = 225/15 = 15 s.
- Boats and Streams
6. Speed of a boat in still water is 14 km/h and stream speed is 4 km/h. Downstream speed is:
- A. 8 km/h
- B. 10 km/h
- C. 14 km/h
- D. 18 km/h (Correct)
Explanation: Downstream speed = 14 + 4 = 18 km/h.
- Relative Speed
7. Two trains running in opposite directions at 54 km/h and 36 km/h cross each other in 12 seconds. If one train is 120 m long, the other is:
- A. 150 m
- B. 160 m
- C. 180 m (Correct)
- D. 200 m
Explanation: Relative speed = 90 km/h = 25 m/s. Total length = 25 x 12 = 300 m, so other train = 180 m.
- Average Speed
8. A person travels 120 km at 40 km/h and returns at 60 km/h. Average speed for the whole trip is:
- A. 45 km/h
- B. 48 km/h (Correct)
- C. 50 km/h
- D. 52 km/h
Explanation: For equal distances, average speed = 2ab/(a+b) = 48 km/h.
- Distance-Time
9. If speed is increased by 25%, time taken to cover the same distance decreases by:
- A. 15%
- B. 20% (Correct)
- C. 25%
- D. 30%
Explanation: New time = 1/1.25 = 80% of old time.
- Train
10. A 120 m train crosses a man walking in the same direction at 3 m/s in 20 seconds. If the train speed is 9 m/s, the man's speed is:
- A. 2 m/s
- B. 3 m/s (Correct)
- C. 4 m/s
- D. 5 m/s
Explanation: Relative speed = 120/20 = 6 m/s, so man's speed = 9 - 6 = 3 m/s.
- Boat
11. A boat covers 36 km downstream in 3 hours and the same distance upstream in 4 hours. Speed in still water is:
- A. 10.5 km/h (Correct)
- B. 11 km/h
- C. 11.5 km/h
- D. 12 km/h
Explanation: Downstream = 12 km/h, upstream = 9 km/h, so still water speed = (12 + 9)/2 = 10.5 km/h.
- Speed
12. A runner covers 400 m in 50 seconds. His speed is:
- A. 6 m/s
- B. 7 m/s
- C. 8 m/s (Correct)
- D. 9 m/s
Explanation: Speed = 400/50 = 8 m/s.
