Question
A train 660 metres long is running at a speed of 54
km/hr. If it crosses a tunnel in 1 minute, then the length of the tunnel (in meters) is: TYPE 8Solution
Let the length of the tunnel be ‘x’ meter. Speed = 54 × (5/18) m/sec = 15 m/sec Time = 1 minute = 60 seconds. Let the length of the tunnel be x metres. Then, (660 + x)/60 = 15 =>(660 + x) = 900 => x = 240 m
