Question: Elroy decides to enter a walk-a-thon and wants to make sure he ties last year's winner's cash collection. Last year, walkers earned $4 a mile. This year walkers earn $2.75 a mile. If last year's winner collected $44, how many more miles will Elroy walk than last year's winner to collect the same amount of money?
Solution:
Last year's winner walked 11 miles because 44 / 4 = 11
Elroy has to walk 16 miles to collect $44 because 44 / 2.75 = 16
Elroy will walk 5 more miles because 16 - 11 = 5
Answer: 5
