Answer:
If I am understanding your question, the total upstream is 8 miles and another 8 miles downstream.
Let s = the speed of the boat in still water
d = rt
8 = 5(s + 3) downstream
8 = 5s + 15 equation 1
8 = 5(s - 3) upstream
8 = 5s - 15 Add equation 1
8 = 5s + 15
16 = 10s Divide both sides by 10.
s = 16/10 = 8/5 = 1.6 mph
