  1. A8 km/h
  2. B5 km/h
  3. C3 km/h
  4. D4 km/h
Show answer
Answer: (C) 3 km/h Downstream speed = 11, upstream = 5; stream = (downstream − upstream)/2 = 3 km/h.
Question 8

A train 450 m long is running at 90 km/h. How long will it take to cross a pole?

  1. A15 seconds
  2. B14 seconds
  3. C18 seconds
  4. D22 seconds
Show answer
Answer: (C) 18 seconds Speed = 90 × 5/18 = 25 m/s; time = 450 ÷ 25 = 18 s.
Question 9

A train 110 m long running at 72 km/h crosses a platform in 38 seconds. What is the length of the platform?

  1. A760 m
  2. B650 m
  3. C630 m
  4. D680 m
Show answer
Answer: (B) 650 m Distance covered = 20 × 38 = 760 m = train + platform, so platform = 650 m.
Question 10

A speed of 198 km/h is equal to

  1. A99 m/s
  2. B55 m/s
  3. C712.8 m/s
  4. D50 m/s
Show answer
Answer: (B) 55 m/s Multiply by 5/18: 198 × 5/18 = 55 m/s.

Question 11

A person travels from P to Q at 60 km/h and returns at 40 km/h. What is the average speed for the whole journey?

  1. A50 km/h
  2. B45 km/h
  3. C48 km/h
  4. D53 km/h
Show answer
Answer: (C) 48 km/h For equal distances, average speed = 2ab/(a + b) = 48 km/h.
Question 12

A train 510 m long is running at 108 km/h. How long will it take to cross a pole?

  1. A21 seconds
  2. B17 seconds
  3. C14 seconds
  4. D20 seconds
Show answer
Answer: (B) 17 seconds Speed = 108 × 5/18 = 30 m/s; time = 510 ÷ 30 = 17 s.
Question 13

A train 90 m long running at 36 km/h crosses a platform in 37 seconds. What is the length of the platform?

  1. A280 m
  2. B370 m
  3. C260 m
  4. D310 m
Show answer
Answer: (A) 280 m Distance covered = 10 × 37 = 370 m = train + platform, so platform = 280 m.
