A train 550 metres long is running at a speed of 72
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 = 72 × (5/18) m/sec = 20 m/sec Time = 1 minute = 60 seconds. Let the length of the tunnel be x metres. Then, (550 + x)/60 = 20 =>(550 + x) = 1200 => x = 650 m
