Question
The speeds of train 'A' and 'B' are 14 m/s and 21 m/s,
respectively. Whereas the lengths of train 'A' and 'B' are in the ratio 2:3, respectively. If the trains take 10 seconds to cross each other while travelling in opposite directions, then find the length of train 'A'.Solution
Let the length of trains 'A' and 'B' be '2x' metres and '3x' metres, respectively. ATQ; {2x + 3x}/{14 + 21} = 10
{5x/35} = 10
5x = 350
or, x = 70 So, length of train 'A' = 2x = 2 × 70 = 140 metres
