time from Dehradun and from Delhi, individually towards each other at a speed of 40 km/hr and 30 km/hr individually. At the time of their meeting point, it was found that ‘Alto’ travelled 400 km more than ‘Swift’, then what will be the distance between Dehradun and Delhi.Solution
ATQ, we can say that Let, Distance travelled by ‘Swift’ = 'x' km Distance travelled by ‘Swift’ = ('x' + 400) km According to the question, Time for which 'Alto' car travelled = Time for which 'Swift' car travelled Or, (x/30) = {(x + 400)/40} Or, 4x = 3x + 1200 Or, x = 1200 The distance between Dehradun and Delhi = 1200 + 1200 + 400 = 2800 km
