While following the directions on a treasure map, a pirate walks 45.0 m north and then turns and walks 7.5 m east. What single straight-line displacement could the pirate have taken to reach the treasure?

Displacement = 45.62 m

Explanation:

Given that,

A pirate walks 45.0 m north and then turns and walks 7.5 m east.

We need to find the straight-line displacement taken to reach the treasure. We know that the displacement covered by an object is equal to the shortest path covered by it. It can be given by :

So, the displacement taken to reach the treasure is 45.62 m.

that would be b i just took the test : )
