Answer:
4545 kl/meter
Step-by-step explanation:
Length of the train
=
150 m
travelling speed= 30km/hr
Relative speed =45sec
= 150 × 3okm/hr
= 4500 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 + travelling speed
= 4500+45 km/hr
= 4545 km/hr
Hope this helps
