A vehicle runs on a straight road of length 'L'. It travels half the distance with speed V and the remaining distance with speed 3V 2 . Its average speed is

Options

  1. A4V 3
  2. B3V 4
  3. C5V 6
  4. D6V 5

Correct answer

D. 6V 5

Step-by-step solution

Total distance is L . Time taken to travel the first half distance is t₁ = L/2 V = L 2V . Time taken to travel the second half distance is t₂ = L/2 3V/2 = L 3V . Total time taken is t = t₁ + t₂ = L 2V + L 3V = 5L 6V . Average speed is v_ avg = Total distance Total time = L 5L 6V = 6V 5 . Answer: 6V 5
