Kinematics Question 389

Question: A bus is moving with a velocity of $ 10m{{s}^{-1}} $ on a straight road. A scootor it’st w it’shes to overtake the bus in one minute. If the bus is at a distance of 1.2 km ahead, then the velocity with which he has to chase the bus it’s

Options:

A) $ 20m{{s}^{-1}} $

B) $ 25m{{s}^{-1}} $

C) $ 60m{{s}^{-1}} $

D) $ 30m{{s}^{-1}} $

Show Answer

Answer:

Correct Answer: D

Solution:

Speed to cover 1200 m by scootar it’st $ V _{r}\times 60=1200\Rightarrow v _{r}=20 $

Speed to overtake bus $ v=v _{r}+10=30\text{ m/s} $
