Answer:Distance from Seattle to wilderness = 7392 miles.Step-by-step explanation:A private plane traveled from Seattle to a rugged wilderness, at an average speed of 312 mph. On the return trip, the average speed was 364 mph. Total travel time = 44 hoursLet the distance from Seattle to wilderness be s. [tex]\texttt{Time of Seattle to wilderness = }\frac{s}{312}\\\\\texttt{Time of wilderness to Seattle = }\frac{s}{364}[/tex]We have [tex]\frac{s}{312}+\frac{s}{364}=44\\\\364s+312s=44\times 312\times 364\\\\676s=4996992\\\\s=7392miles[/tex]Distance from Seattle to wilderness = 7392 miles.
