A train 200 metres long passes through a tunnel of 1.3 km. If speed of the train is 20 m/s then how long the train will take to come out of the tunnel completely?

**(A)** 60 seconds

**(B)** 50 seconds

**(C)** 40 seconds

**(D)** 30 seconds

**(E)** None of the above

Total distance to be covered = length of the train + length of the tunnel = 200 m + 1300 m = 1500 m

Speed of the train = 50 m/s

Distance = speed time

seconds

Hence, the answer is **(D)**.
