Question 821542: A boat traveled 288 miles downstream and back. The trip downstream took 12hours. The trip back took 72 hours. Find the speed of the boat in still water and the speed of the current. Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! ---
s = d / t
---
down:
s + w = 288/12 = 24
---
up:
s - w = 288/72 = 4
---
put the system of linear equations into standard form
---
x + y = 24
x - y = 4
---
copy and paste the above standard form linear equations in to this solver:

answer:
x= speed of boat in still water = 14 mph
y= speed of water = 10 mph
