So hmm the distances are clearly 6km and 15km anyway
so hmmm alrite.. recall your d = rt, or distance = rate * time
if the rate of speed of the tourist's boat is say "r", on the river, against the stream, is not going to be "r" but we have to subtract the river's speed, since we know is "2", thus the speed of the boat is " r - 2"
now, off he goes on the lake, however, the lake is just still water, so, on still water, his speed is indeed just "r"

Besides, the land around the Mississippi river is some of the most fertile in the world, specially in the areas around what is now Iowa and Illinois, two states that are part of the agricultural hinterland of the United States.
