Let
x---------> the rate of the boat in still water in mph
y--------> the rate of the current in mph
we know that
Upstream
equation 
Downstream
equation 
Adds equation and equation
Find the value of y
therefore
the answer is
the rate of the boat in still water is 
the rate of the current is 
Answer: yes
Step-by-step explanation:
You’re multiplying every x value by 4 to get the y values
(Someone got mad at me for not including a better explanation so here you go:
x = 3 y = 12..... 3(k) = 12 (divide both sides by three)
k = 4
x = 5 y = 29..... 5(k) = 20 (divide both sides by five)
k = 4
So on and so forth for the rest of the table
