Suppose you walk 13.0 m straight west and then 25.0 m straight south. How far are you from your starting point (in m)

28.2 m

Explanation:

Applying,

Pythagoras theorem,

a² = b²+c² Equation 1

Where a = The distance from my starting point to my current point, b = distance walked due west, c = distance walked due south

From the question,

Given: b = 13 m, c = 25 m

Substitute these values into equation 1

a² = 13²+25²

a² = 169+625

a² = 794

a = √794

a = 28.18 m

a ≈ 28.2 m
