A train of length 200 m traveling at `30 ms ^(-1)` overtakes another train of length 300 m traveling at `20 ms ^(-1).` The time taken by the first train to pass the second is

A

30 s

B

10 s

C

50 s

D

40 s

Text Solution

Verified by Experts

The correct Answer is:
C
Total distance travelled = 300 + 200 = 500 m
Relative velocity `=30 - 20 = 10 m//s`
Time taken `=500/10 =50s`
