Speed of a boat during upstream is 13 km/hr & speed of current is 7 km/hr Then find speed(km/hr) of boat during downstream?

In a river, the ratio of the speed of stream and speed of boat in still water is 2:5. Again, the ratio of the speed of stream and speed of another boat in still water is 3:4. What is the ratio of speeds of the first boat to the second boat in still water?

A motor boat, whose speed is 15 km/hour in still water goes 30 km downstream and comes back in a total of 4 hour and 30 minutes. The speed of the stream is:

A man rows 32 km downstream and 14 km upstream, and takes 6 hours to cover each time. What is the speed of the current?

A man can row at a speed of  km/hr. in still water. If he takes 4 times as long to row a distance upstream to row the same distance downstream, then the speed of stream (in km/hr) is:

A boat takes quarter times in moving a certain distance downstream than upstream. The ratio of the boat in still water and that of the current is

On a river, B is the midpoint between two points A and C on the same bank of the river. A boat can go from A to B and back in 14 hours and from A to C in 18 hours 30 minutes. How long would it take to go from C to A?

The speed of motor-boat to that of current of water is 48 : 17. The boat goes along with the current in 5 hours 10 minutes. It will come back in –
