Question

A bird leaves its nest and flies 10 km due west. The bird then flies 19 km due north. What is the shortest distance from the bird to its nest? Round to the nearest tenth of a km.

Answer 1

21.5 km

Explanation:

Pythagorean Theorem: shortest distance is hypotenuse

Legs: 10 km, 19 km

10^2+19^2=c^2

100+361=c^2

c=sqrt(461) = 21.4709105535838885 approx. 21.5
