A maritime logistics student is learning to solve river current problems. Arrange the steps of the problem-solving strategy in the correct order to find the speed of a ship and the current using the elimination method.

A logistics coordinator for a river transport company is training new staff on how to model vessel speeds for scheduling. Match each algebraic expression or variable to the specific component of the motion model it represents, where 's' is the speed of the vessel in still water and 'c' is the speed of the river current.

A maritime logistics analyst is using the following system of equations to determine a transport ship's speed ($s$) and the river current ($c$). According to the problem-solving strategy for the elimination method, which mathematical property must be applied first to transform these equations into standard form?

$\begin{cases} 4(s + c) = 60 \\ 5(s - c) = 60 \end{cases}$

A river transport coordinator is calculating the travel time for a cargo barge. If $s$ represents the speed of the barge in still water and $c$ represents the speed of the river current, the algebraic expression used to represent the barge's total speed while traveling upstream (against the current) is ________.

In the context of river transport logistics, when using the elimination method to solve a system of equations such as $20s + 20c = 300 and $20s - 20c = 240, adding the two equations together eliminates the variable representing the current ($c$) because its coefficients are additive opposites.

A river transport logistics coordinator is setting up a mathematical model for vessel scheduling. To represent a ship traveling downstream for 2 hours to cover a distance of 40 miles, which equation is in the standard form ($As + Bc = C$) required for the elimination method? (Let $s$ represent the speed of the ship in still water and $c$ represent the speed of the current.)

A river transport logistics coordinator is training new staff on the standard seven-step procedure for modeling vessel speeds. Match each step of the problem-solving strategy with its corresponding action in the algebraic modeling process.
