A soccer ball moves from point A to point B. Then, it moves to point C. Find the distance between points A and C along the grid.
For the horizontal direction:
Point A is 8 grids away from zero.
Point C is 1 grid away from zero.
So, the distance between the points A and C, along the horizontal direction, is = 8 - 1 = 7 grids.
For the vertical direction:
Point A is 3 grids away from zero.
Point C is 9 grids away from zero.
So, the distance between the points A and C along the vertical direction is = 9 - 3 = 6 grids.
∴ Total distance = 7 + 6 = 13 grids
Hence, the distance between points A and C is 13 grids.
