Suppose pq represents the distance, and s represents the speed of the boat.
Downstream, the equation for the travel time is
pq/(s + s/2) = 2
pq = 2(3/2s)
pq = 3s
Upstream, the equation for the travel time is
pq/(s - s/2) = 6
pq = 6(s/2)
pq = 3s
There is insufficient information given to find the actual distance. We can only say it is the distance the boat would travel in still water in 3 hours.
