If you have (n) gaps in a pit / pathway etc., then you're going to need to place (n-1) warps within that space (unless it's a 1x1 gap in which case you still need 1 warp).
For example, you'd need 1 warp for a hole of width 2, 2 warps for a hole of width 3, etc. This is because the player can touch any point on a warp and it'll warp them, and the player is 1 tile wide (therefore for example, in a 2 gap hole, you only need 1 warp as the player will always pass through the centre of it).
It is given that x = 5. What is the value of y?
