Calculate Displacement: Cesar's Walk North and West

To find the displacement, we need to find the straight line distance from the starting point to the ending point.

Cesar walks 1 mile north, which means he moves 1 mile in the positive y-direction.

Then, he turns west and walks 2 miles, which means he moves 2 miles in the negative x-direction.

Since the movements are perpendicular to each other, we can use the Pythagorean theorem to find the displacement.

Displacement = √((1^2) + (-2^2)) = √(1 + 4) = √5

Therefore, the displacement is approximately √5 miles.
