Question

Suppose Tommy walks from his home at (0, 0) to the mall at (0, 7), and then walks to a movie theater at (9, 7). After leaving the theater Tommy walks to the store at (9, 0) before returning home. If each grid square represents one block, how many blocks does he walk?

Answer 1

32 blocks

Explanation:

distance between home (0,0) and mall (0,7) = 7

distance between mall (0,7) and movies (9,7) = 9

distance between movies (9,7) and store (9,0) = 7

distance between store (9,0) and home (0,0) = 9

7 + 9 + 7 + 9 = 32 blocks
