A car covers it's journey along a straight line in these equal parts with speed of V1,V2 and V3,recpectively.Find the avg speed of the car.

$answer -$

A car covers a straight line path in three equal parts with avg speed of V1, V2 and V3.

Then its avg speed v is given by-

$v = v {1} + v2 + v3$

$v = \frac{v1 + v2 + v3}{3}$

$(v1 \: v2 \: v3) \frac{1}{3 } = v$

$\frac{1}{v} = \frac{1}{v1} = \frac{1}{v2} = \frac{1}{v3}$

$\frac{3}{v} = \frac{1}{v1} + \frac{1}{v2} + \frac{1}{v3}$
