A person leaves work and travels west for 15 miles. They then turn left and travel south for 10 miles, to their home. If a bird could fly directly from the work to the home, how far would the bird fly

Given:

A person leaves work and travels west for 15 miles.

They then turn left and travel south for 10 miles, to their home.

To find:

Distance between work place and home.

Solution:

The person travels west for 15 miles, then travel south for 10 miles.

It means, it forms a right angle triangle with legs 15 and 10.

To find the distance between work place and home we need to find the hypotenuse of the triangle.

Pythagoras theorem:

Taking square root on both sides.

Therefore, the bird would fly 18.03 miles.

maybe bc of how many times you can add the number itself
