Question

From her home, Giera traveled

5.8 miles north to the grocery
store, then 2.1 miles west to
the library. What is the distance
from her home to the library?

Answer 1

• 6.2 miles

Explanation:

The imaginary lines connecting the home, the grocery store and the library form a right triangle with the distance from the home to the library being a hypotenuse.

Use Pythagorean to find the distance:

• √5.8² + 2.1² = √38.05 = 6.16 ≈ 6.2 miles
