You can put this solution on YOUR website!
let both trains meet each other x hours after second train starts
Time taken by train 1 will be = x+3
distance covered by train 1 = 50(x+3)
Time taken by train 2 will be = x
distance covered by train 2 = 65(x)

bothe distances will be equal
so 65x = 50(x+3)
65x = 50x+150
65x - 50x = 150
15x = 150
x = 150/15
x = 10
ans 10 Hours
