He walks 3 blocks east and then 4 blocks south to get to his friends house. What is his distance? What is his displacement

Distance is 7 blocks and the displacement is 5 blocks.
You add the blocks 3 + 4 to get the distance. And then to get displacement, you add 3 squared (9) and 4 squared (16) to get 25. Then find the square root of 25, which is 5. So your displacement is 5 blocks.

Sorry if you didn’t want a full explanation, I thought it would be best to show the steps :)
