Question

A person travels x distance with velocity v1 and then x distance with velocity v2 in the same direction. The average velocity of the person is v, then the relation between v, v1 and v2 will be

• A. $v=\frac{v_1+v_2}{2}$
• B. V=V1+V2
• C. $\frac{1}{v}=\frac{1}{v_1}+\frac{1}{v_2}$<
• D. $\frac{2}{v}=\frac{1}{v_1}+\frac{1}{v_2}$

Answer 1

Answer: (D)

$\frac{2}{v}=\frac{1}{v_1}+\frac{1}{v_2}$

Answer 2

The correct option is(D ): $\frac{2}{v}=\frac{1}{v_1}+\frac{1}{v_2}$
