Question

The map shows the location of a mall, library, and school in a city:

Sarah traveled from the school to the mall and then from the mall to the library. Bret traveled from the school to the library. How many miles did Sarah and Bret travel altogether?
12 miles
29 miles
41 miles
70 miles

Answer 1

The correct answer is 70 miles!

Explanation:

Answer 2

a (library to mall) = 20
b (mall to school) = 21
c (library to school) =

a^2 + b^2 = c^2
400 + 441 = c^2
841 = c ^ 2
c = 29

a + b + c = 70

The answer is 70 miles
