Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
x = speed of boat in still water
y = speed of current
---
s = d/t
---
downstream:
x + y = 16/2
x + y = 8
---
upstream:
x - y = 16/8
x - y = 2
---
put the system of linear equations into standard form
---
x + y = 8
x - y = 2
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = speed of boat in still water = 5 mph
y = speed of current = 3 mph
