  1. A165 m
  2. B315 m
  3. C215 m
  4. D185 m
Show answer
Answer: (D) 185 m Distance covered = 15 Γ— 21 = 315 m = train + platform, so platform = 185 m.
Question 8

A boat goes 42 km downstream in 3 hours and 12 km upstream in 3 hours. What is the speed of the stream?

  1. A10 km/h
  2. B6 km/h
  3. C5 km/h
  4. D4 km/h
Show answer
Answer: (C) 5 km/h Downstream speed = 14, upstream = 4; stream = (downstream βˆ’ upstream)/2 = 5 km/h.

  1. A10 seconds
  2. B14 seconds
  3. C11 seconds
  4. D12 seconds
Show answer
Answer: (A) 10 seconds Speed = 108 Γ— 5/18 = 30 m/s; time = 300 Γ· 30 = 10 s.
Question 10

A speed of 126 km/h is equal to

  1. A40 m/s
  2. B30 m/s
  3. C63 m/s
  4. D35 m/s
Show answer
Answer: (D) 35 m/s Multiply by 5/18: 126 Γ— 5/18 = 35 m/s.

Question 11

A person travels from P to Q at 30 km/h and returns at 45 km/h. What is the average speed for the whole journey?

  1. A36 km/h
  2. B38 km/h
  3. C37.5 km/h
  4. D41 km/h
Show answer
Answer: (A) 36 km/h For equal distances, average speed = 2ab/(a + b) = 36 km/h.
Question 12

A train 160 m long running at 36 km/h crosses a platform in 32 seconds. What is the length of the platform?

  1. A320 m
  2. B140 m
  3. C190 m
  4. D160 m
Show answer
Answer: (D) 160 m Distance covered = 10 Γ— 32 = 320 m = train + platform, so platform = 160 m.
