Question

A vehicle travels along a straight path between two places A and B. It
travels first half of the distance with a velocity 72 km/h and the
remaining distance with a velocity of 36 km/h. Then the average
velocity (in m/s) of the vehicle is
a) 11.3
b) 13.3
c) 15
d) 14​

Answer 1

Answer:

c) 15

Step-by-step explanation:

as the average velocity  of an object = Total Displacement

                                                                 Total time taken

here they gave velocities 72 km/h and 36 km/h

if we convert them into m/s we get 20m/s and 10m/s

now the average velocity = $\frac{20+10}{2}$= $\frac{30}{2}$= 15

so the answer is 15 which is option c

Answer 2

The above answer is wrong.
