8 minus current, times time1 is distance traveled up

8 plus current, times time2 is distance traveled down

when the distances equal .... we know the current

3(8-c) = 2(8+c)

24 -3c = 16 + 2c

24 - 16 =  5c

c = (24-16)/5

so im not real sure what the extra conflagration is all about
