Question

The streets in Sachi's city are arranged in square blocks. Sachi left her house and walked 5 blocks east and 2 blocks north to Jim's house. She and Jim walked 1 block north, 3 blocks west and 2 blocks south to Bella's house. How far from Bella's house is Sachi's house?

Answer 1

Sachi goes 5 blocks to the right(east) and 2 blocks up(north). From there, add 1 block up, and 3 blocks to the left(west). And then, 2 blocks down (south). So, we are left with: 
2 Blocks to the left (west) and 1 block down (south) to reach back to Sachi's house.
