Question

If a car covers $2/5^{th}$ of the total distance with $v_1$ speed and $3/5^{th}$ distance with $v_2$ then average speed is

A

$\frac{1}{2}\sqrt{\nu_1 \nu_2}$

B

$\frac{\nu_1+\nu_2}{2}$

C

$\frac{2\nu_1 \nu_2}{\nu_1+\nu_2}$

D

$\frac{5\nu_1 \nu_2}{3\nu_1+2\nu_2}$

Answer

$\frac{5\nu_1 \nu_2}{3\nu_1+2\nu_2}$

Explanation

Solution

$Avg$ speed = $\frac{total \, distance}{total \, times}$
