D(x) = 1375 - 110x.....where x is the hrs traveled and d(x) is the distance in miles left to travel

(a) after 8 hrs....so x = 8
d(8) = 1375 - 110(8)
d(8) = 1375 - 880
d(8) = 495...so after 8 hrs, u r 495 miles short of ur destination

(b) before reaching its destination...its destination is 1375 miles....and if u r traveling 110 miles per hr....1375/110 = 12.5....so after 12.5 hrs, u should reach ur destination.
