A man walked 9 km towards East and then 12 km towards South. How far is he from the starting point?
15 km
We can apply the Pythagorean theorem here. The man has walked 9 km east and 12 km south. These form two sides of a right triangle, with the hypotenuse being the straight-line distance from the starting point.
The formula for the hypotenuse is:
Hypotenuse = √(9² + 12²) = √(81 + 144) = √225 = 15 km
The man is 15 km away from the starting point.
