Question

A ship left the port and sailed 40 kilometers south, then 36 kilometers north. What integer represents where the ship is located in reference to zero (the port)?

Answer 1

4 because if the ship went 40 kilometers south, then 36 north, it would be traveling back to its starting point, so tok would subtract 36 from 40 and get 4. Hope this helped!!

Answer 2

It would be at -4 or (coordinates: 0, -4)

Explanation:

0 - 40 = -40

-40 + 36 = -4

so -4
