2 answers:
She walked 56 miles to the mall, 14 miles at the mall, then 56 miles back home. Total=126 miles.
Yes she is proved. 126 miles is more than 2 miles.
56 mile should be 5/6 mile
14 mile should be 1/4 mile
5/6 + 5/6 + 1/4 = 1 11/12 miles.
5/6 is added twice becaue Maria walked the path twice. Going to the mall and Coming from the mall.
(5/6 * 2/2) + (5/6 *2/2) + (1/4 *3/3) = 10/12 + 10/12 + 3/12 = 23/12
<span>23/12 = </span>1 11/12 miles.
Maria did not walk more than 2 miles. She only walked 1 11/12 miles.
