Question

A particle covers half of the total distance with
velocity v. On the remaining
part, it moves with 20
for one third of the time and with 3v for two third
of the time. What is the overall average velocity of
the particle?
​

Answer 1

Answer:

Correct option is

C

v1+v22v1v2

If The half distance (x) covered with the speed v1 in t1 time.

Using formula of speed, v1=t1x

so, t1=v1x

And another half distance (x), covered with speed v2 in time t2.

so, v2=xt2

t2=v2x

Average Velocity=Total timeTotal distance

Total time=t1+t2=v1x+v2x
