16 feet of fabric left on the roll. take 9 yards turn it into feet (times three to get feet) then do the same for 2 1/3. 9 yards becomes 27 feet and 2 1/3 yards becomes 7 feet. add 7 feet plus four. you get positive eleven. Then take 27 feet minus 11, you get 16 feet or 5 1/3 yards of fabric
So if he already biked 25 miles we can subtract 80 and 25 which will get a total of 55. if we divided 55 miles to the rest of the 5 days he will have to bike 11 miles each day
