Solution

Velocity can vary when speed is constant.
Because when people are moving either up or down at the same rate, their speed is the same but velocities are different because their direction will be different.
Hence velocity can vary when speed is constant.

Q. Two boys enter a running escalator on the ground floor in a shopping mall and they do some fun on it. The first boy repeatedly follows

p_{1} = 1

step up and then

q_{1} = 2

steps down whereas the second boy repeatedly follows

p_{2} = 2

steps up and then

q_{2} = 1

step down. Both of them move relative to escalator with speed

v_{r} = 50 c m s^{- 1}

. If the first boy takes

t_{1} = 250 s

and the second boy takes

t_{2} = 50 s
