Answer:
11.4
Explanation:
Assuming you are looking for the line of displacement, we know that the end result will look in the shape of a right triangle, so the line of displacement is the hypotenuse.
You drive west (left) for 3 miles, then north (up) for 11 miles. To find the hypotenuse of this right triangle, we can use the Pythagorean Theorem, which states 'a² + b² = c².'
We can put 3 in for a, and 11 in for b.
3² + 11² = c²
9 + 121 = c²
130 = c²
c = √130
c ≈ 11.4
