Let’s solve this step by step.
We are given two points on a coordinate plane:
- Point A is at (1, 1) → that means x = 1, y = 1
- Point F is at (1, 5) → that means x = 1, y = 5
Notice something important: both points have the same x-coordinate (x = 1). That means they are lined up vertically — one directly above the other.
To find the distance between them, we just need to see how far apart they are in the vertical direction (along the y-axis).
Point A is at y = 1
Point F is at y = 5
So, subtract:
5 - 1 = 4 units
The problem says: “If 1 unit = 1 km”
That means 4 units = 4 km
✔ Double-check:
From y=1 to y=5, you go up 4 steps. Each step is 1 km. So yes, 4 km total.
Final Answer:
4 km
