Question

Maria lives 56 mile from the mall. On Saturday, she walked from her house to the mall and then back again. At the mall, she walked 14 mile while shopping. Maria thinks she walked more than 2 miles on Saturday. Prove or disprove Maria's conjecture.

Answer 1

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.

Answer 2

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
23/12 = 1 11/12 miles.

Maria did not walk more than 2 miles. She only walked 1 11/12 miles.
