Can you tell me if this approach is right. Is there any other way to solve this
1. x =48
y/48 + (40-y)/60 = (y+160)/240
If the speed is the same then 40/48
but since we dont know the value of y. Its not possible.
2. y=20
20/x + 20/1.25x = 44/1.25x
if same speed 40/x.
percentage change , x cancels out, hence B
