(A) 36.6 m
(B) 41.6 m
(C) 43 m
(D) 76.3 m
Correct Option is: B
Speed of person = 10km/hr
As the train and the running person are moving in opposite direction,therir speed values are added to find
the relative speed.
Relative speed = speed of train + speed of person
25 = speed of train
Speed of train = 25 – 10
= 15 km/hr
Convert km/hr into m/s
15 km/hr = (15 * 5 / 18)m/s
= 25 / 6 m/s
Distance = speed * time
= 25 / 6 * 10
= 250/6 m/s
= 41.6 m
