PLEASE HELP ASAP! IF YOU GET RIGHT, I WILL MARK BRAINLIEST!!!

A boat can travel 15 mph with no current. the boat travels 24 miles upstream against the river current at the same time that it later takes traveling 36 miles downstream with the current. Assuming the river current speed is constant, what is the speed of the river current?
(You will use the fact that is b is the speed of the boat with no current and c is the speed of the current, the speed of the boat going upstream is b-c and the speed of the boat going downstream is b+c.) For full credit, you must define a variable, write an equation, solve the equation and answer the question.

b-(4)(36)c+15=6

Step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
