Answer:
![\huge\boxed{P_\triangle=10y+1}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BP_%5Ctriangle%3D10y%2B1%7D)
Step-by-step explanation:
The formula of a perimeter of a triangle:
![P_\triangle=a+b+c](https://tex.z-dn.net/?f=P_%5Ctriangle%3Da%2Bb%2Bc)
We have:
![a=3y+5,\ b=6y,\ c=y-4](https://tex.z-dn.net/?f=a%3D3y%2B5%2C%5C%20b%3D6y%2C%5C%20c%3Dy-4)
Substitute:
![P_\triangle=(3y+5)+(6y)+(y-4)=3y+5+6y+y-4](https://tex.z-dn.net/?f=P_%5Ctriangle%3D%283y%2B5%29%2B%286y%29%2B%28y-4%29%3D3y%2B5%2B6y%2By-4)
Combine like terms:
![P_\triangle=(3y+6y+y)+(5-4)=10y+1](https://tex.z-dn.net/?f=P_%5Ctriangle%3D%283y%2B6y%2By%29%2B%285-4%29%3D10y%2B1)
<span>This problem is solved using dimensional analysis. It is known that there are 5280 yards in a league and that there are 3 feet in one yard. Finally, it is known that there are 6076 feet in one nautical mile. As a result, we can multiply these dimension together, making certain that the units cancel and leave us with only nautical miles.
It is done as follows:
(610 leagues)(5280yds/1 league)(3 ft/1yd)(1 nautical mile/6076ft)= 1590 naurtical miles.</span>
