A train has a length of 150 metres.
A train has a length of 150 metres. It is passing a man who is moving at 22 km/hr in the same direction of the train, in 33 seconds. Find out the speed of the train.
Answer/Solution
182 km/hr
Steps/Work
Explanation:
Length of the train =150=150 m
Speed of the man =2=2 km/hr
Relative speed =1503=50 m/s=1503=50 m/s
=50×185=180 km/hr=50×185=180 km/hr
Relative speed = Speed of train - Speed of the man (as both are moving in the same direction). Therefore,
Speed of the train = Relative speed + Speed of the man
=180+2=182 km/hr=180+2=182 km/hr
ANSWER IS A
Length of the train =150=150 m
Speed of the man =2=2 km/hr
Relative speed =1503=50 m/s=1503=50 m/s
=50×185=180 km/hr=50×185=180 km/hr
Relative speed = Speed of train - Speed of the man (as both are moving in the same direction). Therefore,
Speed of the train = Relative speed + Speed of the man
=180+2=182 km/hr=180+2=182 km/hr
ANSWER IS A
