Relative speed = (50 + 52) km/h = (102 x 5/18) m/s = (255/9) m/s.

Distance covered in crossing each other = (165 + 175) = 340 m.
∴ Required time = (340 x 9/255) = 12 s.

To find the time it takes for the two trains to cross each other, we need to consider their relative speed and the total distance they need to cover.
Given:
Length of the first train (A) = 165 m
Length of the second train (B) = 175 m
Speed of the first train = 50 km/h
Speed of the second train = 52 km/h
Step 1: Convert the speeds from km/h to m/s.
Speed of the first train = 50 km/h = (50 * 1000) / 3600 m/s = 50000 / 3600 m/s = 13.89 m/s
Speed of the second train = 52 km/h = (52 * 1000) / 3600 m/s = 52000 / 3600 m/s = 14.44 m/s
Step 2: Calculate the relative speed of the two trains.
Relative speed = Speed of first train + Speed of second train
Relative speed = 13.89 m/s + 14.44 m/s = 28.33 m/s
Step 3: Calculate the total distance the two trains need to cover to cross each other.
Total distance = Length of first train + Length of second train
Total distance = 165 m + 175 m = 340 m
Step 4: Calculate the time taken to cross each other.
Time = Distance / Relative speed
Time = 340 m / 28.33 m/s ≈ 12 seconds
Therefore, the two trains take approximately 12 seconds to cross each other.
Answer: Option D) 12
Given:
Length of the first train (A) = 165 m
Length of the second train (B) = 175 m
Speed of the first train = 50 km/h
Speed of the second train = 52 km/h
Step 1: Convert the speeds from km/h to m/s.
Speed of the first train = 50 km/h = (50 * 1000) / 3600 m/s = 50000 / 3600 m/s = 13.89 m/s
Speed of the second train = 52 km/h = (52 * 1000) / 3600 m/s = 52000 / 3600 m/s = 14.44 m/s
Step 2: Calculate the relative speed of the two trains.
Relative speed = Speed of first train + Speed of second train
Relative speed = 13.89 m/s + 14.44 m/s = 28.33 m/s
Step 3: Calculate the total distance the two trains need to cover to cross each other.
Total distance = Length of first train + Length of second train
Total distance = 165 m + 175 m = 340 m
Step 4: Calculate the time taken to cross each other.
Time = Distance / Relative speed
Time = 340 m / 28.33 m/s ≈ 12 seconds
Therefore, the two trains take approximately 12 seconds to cross each other.
Answer: Option D) 12
