Question #3






Walter walks across a rectangular field in a diagonal line. Maria walks around two sides of the field. They meet at the opposite corner.

a) How far did Maria walk ?
I didn't really know how to find the length of what Maria walked so I added together the side lengths...

120 + 300 = 420
Maria walked 420m


~~~~~~~~~~~~~~~~~~~~~~~
b) How far did Walter walk ?

I used the Pythagorean relationship to find the answer...

a² + b² = c²

120² + 300² = c²

( 12o x 120) + ( 300 x 300) = c²

14400 + 90000 = c²

10 4400 = c²

√ 104400 = √ c²

323.1 = c

Walter walked 323.1m.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


c) who walked farther ? by what distance ?

Maria walked farther by ... 96.9m

420 - 323.1 = 96.9m
