<PRE><B>Question 551291</B>
In Red River, Katen can row 12 km downstream in 45 minutes or she can row 1.5 km upstream in the same amount of time. Find the rate she rows in still water and the rate of the current.
-------------------
12 km downstream in 45 minutes 
d = r*t
r = d/t = 12/45 = 4/15 km/minute
= 16 km/hr
-------------
1.5 km upstream in 45 mins
= 0.0333 km/minute 
= 2 km/hr
----
r = her rowing speed
c = current
---
r + c = 16
r - c = 2
You can finish it
