Step-by-step explanation:
im rushing so i may have did it wrong sorry
You multipy 7/8 and 6 and then simplify if needed to get how long it will take
A = (a + b)/2 * h
4 = (a + b)/2
(a + b) = 8
(1+7), (2+6), (3+5), (4+4)
Therefore there are 4 possibilities.
I might be wrong but, I would say about 32.6 miles a day. This could be wrong.
