Length of a Train.
T = (LT+LP)/S
LT = LENGTH OF A TRAIN = ?
LP = LENGTH OF A PLATFORM = 0
S = SPEED = (60*5)/18 = 50/3
T= TIME= 9.
NOW AS PER THE QUESTION.
9 = (?+0)/ (50/3),
=> ? = (9 * 50)/3 = 150 M.
T = (LT+LP)/S
LT = LENGTH OF A TRAIN = ?
LP = LENGTH OF A PLATFORM = 0
S = SPEED = (60*5)/18 = 50/3
T= TIME= 9.
NOW AS PER THE QUESTION.
9 = (?+0)/ (50/3),
=> ? = (9 * 50)/3 = 150 M.

Train of length = x.
Speed of train is 60km/hr.
1km is 1000 * 60 =60000.
1hr is 60 minutes * 1hr =3600.
60000 ÷ 3600=16.6667.
Said that 9sec crosses a pole ,then
X = 16.667 * 9sec = 150m.
Distance = speed * time.
Speed of train is 60km/hr.
1km is 1000 * 60 =60000.
1hr is 60 minutes * 1hr =3600.
60000 ÷ 3600=16.6667.
Said that 9sec crosses a pole ,then
X = 16.667 * 9sec = 150m.
Distance = speed * time.
