<PRE><B>Question 457196</B>
Speed times time = distance

where speed = Speed in still water minus speed of river

            = 2.2 - .8
            = 1.4

Let t = the number of hours it will take Fram to swim 1.4 km upstream

    t = distance / speed
    t = 1.4/1.4
    t = 1

It will take Fran 1 hour to swim 1.4 km upstream.
