A train crosses a stationary pole completely in 18 seconds and a bridge completely in 44 seconds. If the length of bridge is 650 metres, then what is the length of the train ?

450 m

Train crosses a pole in 18 seconds & Train crosses a bridge of length 650 m in 44 seconds .

So , Train takes ( 44 - 18) = 26 seconds to cross 650 m

Speed = \(\frac{650}{26}\) = 25 m/sec

Length of train = 25 × 18 = 450 m
