a motor vehicle travel the first third of a distance at a speed of V1

1.	a motor vehicle travel the first third of a distance at a speed of V1 is equal to 10 kmph the second third at the speed of V2 is equal to 20 kmph and the last third at a speed of V 3 is equal to 60kmph. determine the mean sped of the vehicle over the entire distance s.
Answer» EXPLANATION: average speed(V)= $\frac{3v1v2v3}{v1v2 + v2v3 + v3v1}$ by USING the above formula you will get the MEAN speed as 1860km/hr

EXPLANATION:

average speed(V)=

$\frac{3v1v2v3}{v1v2 + v2v3 + v3v1}$

by USING the above formula you will get the MEAN speed as 1860km/hr
