Julia paddleboat travels 2km/h in stilll water. The boat is paddled 4km down stream in the same time it takes to go 1km upstream what is the speed of the river.

Question

Please help and show all work I suck at story problems haha

Answer 1

ha ha

if you can read, just put it into math. If the river's speed is x, then since time = distance/speed,

4/(2+x) = 1/(2-x)
