Question 33731: A boat travels 60 km downstream in the same time that it takes to go 36 km upstream. The speed of the boat in still water is 12 km/h. Find the speed of the stream and the time it took to travel 60 km downstream. Could someone help me with this problem? Thank you.

Let the speed of the stream be x
Equation:
Upstream -->12+x Downstream -->12-x
Equation:
36(12+x)=60(12-x)
432+36x=720-60x
288=96x
x=3
Hence, the speed of the stream is 3mph.
PAul.
