Please help me with part b of number 16.

You want to find the time (x) when the distance from desitnation is 0:
d = 0,
d(x) = 1375 - 110x 0 = 1375 - 110x 110x = 1375 x = 1375/110 x = 12.5 hrs

To determine when a distance function reaches zero, use the formula t = v d 0 ​ ​ , where d 0 ​ is the initial distance and v is the speed. For instance, with d 0 ​ = 1375 and v = 110 , you find t ≈ 12.5 hours . Plug in the numbers relevant to your question to solve it similarly.
