the Steamship floated on a watercourse 24 km in 2 hours, and the same distance in the opposite direction - in 3 hours. What speed (in kmch) watercourses x- in (kmch) y watercourse speed - in (kmch) own speed the steamship in still water then 24 / (y+x) the =2nd time in hours spent for a way on a watercourse 24 / (y-x) =3 time in hours, spent for a way on a watercourse 12=y+x 8=y-x ⇔4=2x by x=2
