Answer:
B is rate of boat=10 mph
W is rate of river/water=3 mph
(B-W)Tu=D <--equation for traveling upstream
(10-3)Tu=32
7Tu=32
Tu=32/7 hrs or 4.6 hrs
Additional notes:
If you were traveling downstream, your equation would look like this: (B+W)Td=D

Step-by-step explanation:
X^2-6x=13
(x-3)^2-9=13
(x-3)^2=22
(x-3)= +-sqrt22
x = sqrt22+3 or x = -sqrt22+3
Answer:
