Answer:
Let the additional weight that can be added be = x
Current weight of the bag = 38 pounds
Total weight can be = 50 pounds
The equation becomes:
38+x < or equal 50
x < or equal 50-38=12
Hence, a weight of 12 pounds cab be added to the current wight.
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
