arithmetic - two trains of equal length are running on parallel lines in the same direction at 46 kmhr and 36 kmhr if the faster train passes the slower train in 36 secondswhat is the length of each train - skillgun

Assume the length of each train = x
Total distance covered for overtaking the slower train = x+x = 2x
Relative speed = 46-36 = 10km/hr = (10×10)/36 = 100/36 m/s
Time = 36 seconds
2x/ (100/36) = 36
=> (2x × 36 )/100 = 36
=> x = 50 meter
