A boat runs at 22 km per hour along the stream and 10 km per hour against the stream .Find the ratio of the speed of the boat in still water to that of the speed of the stream .
Two boats go downstream from point X to Y. The faster boat covers the distance from X to Y, 1.5 times as fast as slower boat. It is known that for every hour slower boat lags behinds the faster boat by 8 km. however, if they go upstream, then the faster boat covers the distance from Y to X in half the time as the slower boat. Find the speed of the faster boat in still water?
