Question

Anna walks to the library to meet Emma. After walking to the tree house, both girls walk to Emma's house. Later, Anna walks home by herself. Anna is only allowed to walk on the sidewalk. She is not allowed to take shortcuts. If each unit on the grid equals one city block, how many blocks have Anna walked in all?

A) 31 blocks
B) 35 blocks
C) 38 blocks
D) 40 blocks

Answer 1

Anna first walks to the library. This is 7 blocks.

Then she walks 12 blocks to the tree house.

If she takes a route to Emma's house by going up then left, she would walk 3 + 7 = 10 blocks.

Then she walks back home, which is 9 blocks.

Total, Anna walks 7 + 12 + 10 + 9 = 19 + 19 = 38 city blocks total
