Question

A car covers one third part of its straight path with speed V₁ and the rest with speed V₂ . What is its average speed ?

$\frac{3 v_{1} v_{2}}{2 v_{1} + v_{2}}$
$\frac{2 v_{1} v_{2}}{3 v_{1} + v_{2}}$
$\frac{3 v_{1} v_{2}}{v_{1} + 2 v_{2}}$
$\frac{3 v_{1} v_{2}}{2 v_{1} + 2 v_{2}}$

The correct answer is: $fraction numerator 3 v subscript 1 v subscript 2 over denominator 2 v subscript 1 plus v subscript 2 end fraction$
