Speed of car A is 40 m/s and speed of car B following car A is 50 m/s. How long will it take for both the cars to meet if the distance between them is 500 metres.
(A) 10 seconds
(B) 20 seconds
(C) 50 seconds
(D) 30 seconds
(E) None of the above
Speed of car A = 40 m/s
Speed of car B = 50 m/s
Both the cars are moving in the same direction. So, relative speed
m/s
Time = Distance/Speed
seconds
Therefore, it will take 50 seconds for both the cars to meet.
Hence, the answer is (C).
