Car A and car B are coming towards each other with the speed of 40 m/s and 50 m/s respectively. How long will it take for both the cars to meet if the distance between them is 900 metres.
(A) 90 seconds
(B) 30 seconds
(C) 20 seconds
(D) 10 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 opposite directions. So, relative speed
m/s
Time
seconds
Therefore, it will take 10 seconds for both the cars to meet.
