A Man rows to a place 63 km far and comes back in 16 hours. He finds that he can row 18 km with the flow in the same time taken to row 14 km against the flow. What is the speed of the stream?

A boat covers 48 km. upstream and 72 km. downstream in 12 hours, while it covers 72 km. upstream and 48 km. downstream is 13 hours. The speed of stream is -

A boat goes from A to B in upstream and come back from B to A downstream taking a total time of 3.5 hours. If the speed of boat in still water is 7 km/hr and the speed of stream is 5 km/hr. Find the distance between A and B. 

The speed of a boat in still water 11 km/hr. It can go 12 km upstream and return downstream to the engine point in 2hr 45min. What is the speed of stream?

A boat starts travelling from point P, travels to point Q then returns to point P. The boat takes 12 hours to complete the journey. The speed of the stream is 5 km/hour and the speed of the boat in still water is 10 km/hour. What is the distance between P and Q?

The speed of a boat in still water is 10 km/hr. It covers (upstream) a distance of 45 km in 6 hours. The speed (in km/hr) of the stream is : 

A boat goes 10kms an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/hr) is 

A man can row downstream at a speed of 15 km/h and upstream at 11 km/h. Find his speed in still water and the speed of the current, respectively. [Give both your answers in km/h]
