than as to row down the.same distance in the river. The speed of the current is:

 
 
 
 

6. A man can row upstream at 8 km/hr and downstream at 13 km/hr. The speed of the stream is:

 
 
 
 

7. A boat can travel with a speed of 13 Km/h in still water. If the speed of the stream is 4 Km/h, find
the time taken by the boat to go 68 Km downstream.

 
 
 
 

8. The speed of a boat in still water is 10 Km/h. If it can travel 30 Km downstream and comes back
in a total of 4 hours 30 minutes. Ihe speed of the stream is:

 
 
 
 

9. The speed of a boat in still water is 10 Km/h. If it can travel 26 Km downstream and 14 Km
upstream in the same time, the speed of the stream is:

 
 
 
 

10. A man rows downstream 32 Km and 14 Km upstream. If he takes 6 hours to cover each distance,
then the velocity of the current is?

 
 
 
 

11. A boat covers a certain distance downstream in one hour, while it comes back in 1.5 hours. If the
speed of the stream be 3 Km/h, what is the speed of the boat in still water?

 
 
 
 

12. A motor boat, whose speed Is 15 Km/h in stll water goes 30 Km downstream and comes back in
a total of 4 hours 30 minutes. The speed of the stream is:

 
 
 
 

13. A man can row at 15 Km/h in still water. If the veracity of current is one Km/h and it takes him one
hours to row a place and come back, how far is the place?

 
 
 
 

14. If a boat goes 7 Km upstream in 42 minutes and the speed of the stream is 3 Km/h, then the
speed of the boat in still water is:

 
 
 
 

15. The speed of a boat in still water is 15 Km/h and the rate of current is 3 Km/h. The distance
traveled downstream in 12 minutes is

 
 
 
 

16. A boat takes 90 minutes less to travel 36 miles downstream than to travel the same distance
upstream. If the speed of the boat in still water is 10 m/h, the speed of the stream is:

 
 
 
 

17. Speed of a boat in standing water is 9 Km/h and the speed of the stream is 1.5 Km/h. A man rows
to a place at a distance of 105 Km and comes back to the starting point. The total time taken by
him is:
