Question 1

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?

Question 2

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?

Question 3

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:

Question 4

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?

Question 5

A boat cover 45km in downstream & 16 km in upstream. Boat takes total 9hr cover this Distance. The time taken to cover 18 km in downstream is equal to time taken by boat to cover 8km in upstream. Find speed(km/h) of boat in still water.

Question 6

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:

Question 7

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

Question 8

A boat covers 12 km upstream and 16 km downstream in 5 hours, while it covers 36 km upstream and 18 km downstream in 7 ½ hours. What is the speed of the boat?

Question 9

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?

Question 10

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 –
