Question

In Fayetteville, the library is 3 miles due west of the post office and the zoo is 5 miles due north of the library. What is the distance from the post office to the zoo?

Answer 1

Solution:
According to the given conditions, we can draw a sketch as per the attachment.

To find the distance, we can use the Pythagorean Theorem, i.e., a^2 + b^2 = c^2
or 5^2 + 3^2 = c^2
or 25 + 9 = c^2
or c = √(34)
or c = 5.83 miles

Hence, the distance from the Post Office to the Zoo is 5.83 miles.
