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.
