Answer:
the boat travel one way = 2 x 14.16 = 28.32 miles
Step-by-step explanation:
the return trip only takes 1.7 miles (?) ... is it 1.7 hours (?)
the boat travels 2.5 miles (per hour ?) faster downstream
I calculate it on the assumption of my guess stated above ...
X: represent the boat speed / hour
distance one way = 2X
and Distance also = 1.7 * (x + 2.5 ) on return
2x = 1.7 x + 1.7 * 2.5 = 1.7x + 4.25
0.3 x = 4.25
x = 14.16
the boat travel one way = 2 x 14.16 = 28.32 miles
Solution :
Given :
2y''' + 15y'' + 24y' + 11y= 0
Let x = independent variable
is a differential equation.
If 
It is non homogeneous then,
The general solution = complementary solution + particular integral
If Q(x) = 0
It is called the homogeneous then the general solution = complementary solution.
2y''' + 15y'' + 24y' + 11y= 0
Auxiliary equation,
-1 | 2 15 24 11
<u> | 0 -2 - 13 -11 </u>
2 13 11 0
∴ 
The roots are
So, 
Then the general solution is :
