Kinematics Question 389
A bus is moving with a velocity of $ 10m{{s}^{-1}} $ on a straight road. A scooter wishes 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 is
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 scooter it’st $ V _{r}\times 60=1200\Rightarrow v _{r}=20 $
Speed to overtake bus $ v=v _{r}+10=30\text{ m/s} $
