A train crosses a bridge in 15 secs while it crosses a man standing on a platform in 8 secs. If the speed of train 108 km/hrs, then what will be the time taken by the train to cross a tunnel whose length is 210 meters more than the length of the bridge .
ATQ, we can say that Speed of train is = (108 x 5)/18 = 30 m/s then, the Length of bridge is = 30 x 7 = 210 m then, the Length of tunnel = 210 + 210 = 420 m Length of train 108 × 5/18 = (x + 210)/15 30 × 15 = x + 210 x = 240 meter therefore, the Required time = (240 + 420)/30 = 22 seconds
