Question
Two Sampark Kranthi Express of equal length are coming from different cities and are moving in the same direction on parallel tracks at speed of 80 km/hr and 60 km/hr respectively. The faster train crosses the slower train in 14 seconds. Find the length of each train?
Let the length of each train is X.
Distance covered = 2X (sum of the length of trains)
Relative Speed of faster train= 80 − 60 = 20 km/hr
Relative Speed in m/s = 20 x 5/18 = 50/9 m/s
2X/14 = 50/9
18x = 700
x = 38.88 sec
