Mathematics · Time, Speed and Distance
The total time taken by a boat to go 'x' km upstream and then return back a certain distance downstream is 6 hours. The ratio of the speed of the boat in still water to the speed of the stream is 8 : 1, respectively. If the upstream distance covered is 50 km more than the downstream distance covered and the boat can cover (3x + 60) km in still water in 12 hours, then find the value of 'x'.
