Question

A train, 240 m long crosses a man walking along the line in opposite direction at the rate of 3 km/h in 10 s. The speed of the train is

Answer 1

Step-by-step explanation:

Speed of the train relative to man = (24010)m/sec = 24 m/sec = (24×185) km/sec = 4325km/hrLet the speed of the train be x kmph.Then relative speed = (x+3)kmph∴x + 3 = 4325⇒x=4325−3⇒x=4175=83.4kmph

Speed of the train relative to man = (24010)m/sec = 24 m/sec = (24×185) km/sec = 4325km/hrLet the speed of the train be x kmph.Then relative speed = (x+3)kmph∴x + 3 = 4325⇒x=4325−3⇒x=4175

=83.4kmph
