A train 800 metres long is running at a speed of 78 km/hr. If it crosses a tunnel in 1 minute, then the length of the tunnel (in meters) is :
Speed =[ 78 x ( 5/18 ) ] m/sec = 65/3 m/sec.
Time = 1 minute = 60 sec.
Let the length of the tunnel be x metres.
Then, [ (800 + x )/ 60 ]= 65/3
3(800 + x) = 3900
x = 500.
Hence, option 3 is the correct answer.
