Question 927357: 3- Julie and Eric row their boat ( at a constant speed ) 16 miles downstream for 2 hours, helped by the current. Rowing at the same rate, the trip back against the current takes 8 hours. Find the rate of the current and the rate of the boat in still water?

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
y = speed of current = 3
