Question

A man goes 30km due north and then 40km due east. How far away is he from his initial position?

Answer 1

See attachment for the illustration of the question.

We will use Pythagorean Theorem. to find the diagonal distance from the initial position to the final point. The diagonal will be the hypotenuse in the equation:

a² + b² = c²

c² = 30² + 40²

c² = 900 + 1600

c² = 2500

c = √2500

c = 50 km

Answer He is 50 km away from his initial position.
