Answer:
If each grid square represents one block, then the number of box he walked will be 30 blocks.
Step-by-step explanation:
Tommy walks from his home to the mall and then walks to a movie theater.
His home is at (0,0), the mall is at (0,8) and the movie theater is at (7,8).
Now, distance from (0,0) to (0,8) is 8 units and the distance from (0,8) to (7,8) is 7 units.
So, total distance covered is (8 + 7) = 15 units.
After leaving the theater Tommy walks to the store before returning home.
The store is at (7,0).
Now, the distance from (7,8) to (7,0) is 8 units and the distance from (7,0) to (0,0) is 7 units.
So, total distance covered is (8 + 7) = 15 units.
If each grid square represents one block, then the number of the box he walked will be (15 + 15) = 30 blocks. (Answer)
