Answer:
11 3/4 miles.
Step-by-step explanation:
Converting to improper fractions, the consecutive distances are:
21/4 , 55/8, 17/2
= 42/8, 55/8, 68/8 for Monday, Tuesday and Wednesday.
So the distances have increased by 13/8 miles each day.
Thus number of miles he'll bike on Friday = 68/8 + 2(13/8)
= 94/8
= 11 3/4 miles.
First is -1 and 4, second should be no solution and the third is 2 and 6
