Question

Two trains A and B are moving in the same direction with velocities \(V_A\) and \(V_B\) respectively and a third train C is moving in opposite direction. If velocity of C with respect to B is twice the velocity of A with respect to B, then velocity of A with respect to C is:

• A. \(3(V_A-V_B)\)
• B. \(2(V_A-V_B)\)
• C. \((V_A-V_B)/3\)
• D. \((V_A-V_B)/2\)

Hint:

Always choose one direction positive and assign signs before applying relative velocity formulas.

Answer 1

The Correct Option is A
