MCQ (Single Correct Answer)

-1

A car moves from X to Y with a uniform speed v_u and returns to Y with a uniform speed v_d. The average speed for this round trip is

$$\sqrt {{v_u}{v_d}} $$

$${{{v_d}{v_u}} \over {{v_d} + {v_u}}}$$

$${{{v_u} + {v_d}} \over 2}$$

$${{2{v_d}{v_u}} \over {{v_d} + {v_u}}}$$
