Q1. Two cars start at the same time from two towns 162 km apart and move towards each other at 34 km/h and 47 km/h. After how many hours will they meet?

  1. 4 hours
  2. 1 hours
  3. 2 hours
  4. 2.5 hours
  5. 3 hours
Show answer and solution

Answer: C. 2 hours

They close the gap at 34 + 47 = 81 km/h. Time = 162/81 = 2 hours.

Q2. A person goes to a place at 40 km/h and returns at 36 km/h. Find the average speed for the whole journey.

  1. 39.89 km/h
  2. 34.89 km/h
  3. 40 km/h
  4. 37.89 km/h
  5. 38 km/h
Show answer and solution

Answer: D. 37.89 km/h

Average speed = 2ab/(a + b) = 2 × 40 × 36/76 = 37.89 km/h.

Q3. A car covers 168 km in 4 hours. Find its speed in m/s.

  1. 11.67
  2. 151.2
  3. 42
  4. 9.67
  5. 16.67
Show answer and solution

Answer: A. 11.67

Speed = 168/4 = 42 km/h = 42 × 5/18 = 11.67 m/s.

Q4. Two cars start at the same time from two towns 268 km apart and move towards each other at 24 km/h and 43 km/h. After how many hours will they meet?

  1. 3 hours
  2. 6 hours
  3. 4.5 hours
  4. 4 hours
  5. 6.23 hours
Show answer and solution

Answer: D. 4 hours

They close the gap at 24 + 43 = 67 km/h. Time = 268/67 = 4 hours.

Q5. A person goes to a place at 60 km/h and returns at 40 km/h. Find the average speed for the whole journey.

  1. 60 km/h
  2. 50 km/h
  3. 45 km/h
  4. 48 km/h
  5. 53 km/h
Show answer and solution

Answer: D. 48 km/h

Average speed = 2ab/(a + b) = 2 × 60 × 40/100 = 48 km/h.

Q6. A car covers 630 km in 7 hours. Find its speed in m/s.

  1. 23
  2. 25
  3. 45
  4. 30
  5. 90
Show answer and solution

Answer: B. 25

Speed = 630/7 = 90 km/h = 90 × 5/18 = 25 m/s.

Q7. A person goes to a place at 72 km/h and returns at 60 km/h. Find the average speed for the whole journey.

  1. 70.45 km/h
  2. 62.45 km/h
  3. 65.45 km/h
  4. 67.45 km/h
  5. 72 km/h
Show answer and solution

Answer: C. 65.45 km/h

Average speed = 2ab/(a + b) = 2 × 72 × 60/132 = 65.45 km/h.

Q8. A person goes to a place at 45 km/h and returns at 20 km/h. Find the average speed for the whole journey.

  1. 32.5 km/h
  2. 24.69 km/h
  3. 32.69 km/h
  4. 27.69 km/h
  5. 45 km/h
Show answer and solution

Answer: D. 27.69 km/h

Average speed = 2ab/(a + b) = 2 × 45 × 20/65 = 27.69 km/h.

Q9. Two trains 260 m and 190 m long run at 54 km/h and 36 km/h in opposite directions. How long do they take to cross each other?

  1. 16 s
  2. 90 s
  3. 18 s
  4. 36 s
  5. 21 s
Show answer and solution

Answer: C. 18 s

Relative speed = 54 + 36 km/h = 25 m/s. Time = 450/25 = 18 s.

Q10. A train 370 m long running at 36 km/h crosses a platform 290 m long. How long does it take?

  1. 66 s
  2. 37 s
  3. 99 s
  4. 63 s
  5. 70 s
Show answer and solution

Answer: A. 66 s

Distance = 370 + 290 = 660 m; speed = 36 × 5/18 = 10 m/s. Time = 66 s.

Q11. Two trains 280 m and 300 m long run at 72 km/h and 36 km/h in the same direction. How long do they take to cross each other?

  1. 64 s
  2. 19.33 s
  3. 56 s
  4. 58 s
  5. 61 s
Show answer and solution

Answer: D. 58 s

Relative speed = 72 − 36 km/h = 10 m/s. Time = 580/10 = 58 s.

Q12. A train 350 m long running at 36 km/h crosses a platform 140 m long. How long does it take?

  1. 35 s
  2. 49 s
  3. 46 s
  4. 73.5 s
  5. 53 s
Show answer and solution

Answer: B. 49 s

Distance = 350 + 140 = 490 m; speed = 36 × 5/18 = 10 m/s. Time = 49 s.
