Question
Two trains start from stations M and N at the same time
and travel towards each other at speeds of 90 kmph and 75 kmph, respectively. At the time of their meeting, the first train has traveled 180 km more than the second. Find the distance between the stations M and N.Solution
ATQ, Let the distance traveled by the slower train = x km The distance traveled by the faster train = x + 180 km According to the question, x/75 = (x + 180)/90 90x = 75x + 16200 15x = 16200 x = 1080 km Total distance = 1080 + 1080 + 180 = 2340 km
