Explanation:
Speed of train 1 = 60 km/hr = 50/3 m/s
Speed of train 2 = 48 km/hr = 40/3 m/s
Thus, their relative speed = 90/3 = 30 m/s
Let, Length of train 1 = l
Thus, the length of train 2 will be 0.5 l
Time taken by them to cross each other = 15 s
Thus,
Thus,
Train 1 takes 51s to cross a bridge
Let the length of the bridge be b
Thus,
Hence,
Hence, m
