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

Options

  1. A3 ~V 2
  2. BV
  3. CV 2
  4. D2 ~V 3

Correct answer

C. V 2

Step-by-step solution

Average velocity, V _ avg = 2 ~V ₁ ~V ₂ ~V ₁+ V ₂ Given V ₁= V and V ₂= V 3 V _ avg = 2 V V 3 ~V + V 3 = 2 ~V ^2 3 3 4 ~V = V 2
