Answer:
8 blocks
Step-by-step explanation:
As the north direction is upwards and the south direction is downwards the total distance between the two people 's (Megan and Jake) Â houses will be obtained by adding their distances from the library which is in the middle as shown in the diagram.
Hence total distance between the two houses= 3.5 + 4.5= 8 blocks
Jake and Meagan live 8 blocks apart.
