Answer: (3) 175 m

Explanation:-
Let the length of the second train = X m.
The speeds of the train = 40 km/hr.  and  22 km/hr.

According to the question,
(125 + X ) / (40 – 22) x 5/28 = 60
(125 + X)  x 18 /18 x 5 = 60
(125 + X) / 5 = 60
125  + X = 60 x 5
 125 + X = 300
 X = 300 – 125
X = 175
Then, the length of the train is 175 m

Hence, the answer is (3) 175 m.
