(b) 3 hrs
(c) 2.6hrs
(d) 1.2 hrs
Q6. Speed of a boat along and against the current are 12 km/hr and 8 km/hr respectively. Then the speed of the current in km/hr is:
(a) 5
(b) 4
(c) 3
(d) 2
Q7. A man can swim 3 km/hr in still water. If the velocity of the stream is 2 km/hr, the time taken by him to swim to a place 10 km upstream and back is:
(a) 91/3 hr
(b) 10 hr
(c) 12 hr
(d) 81/3 hr
Q8. A swimmer swims from a point A against a current for 5 minutes and then swims backwards in favour of the current for next 5 minutes and comes to the point B. If AB is 100 metres, the speed of the current (in km per hour) is:
(a) 0.4
(b) 0.2
(c) 1
(d) 0.6

(a) 4.5 km/hr
(b) 4 km/hr
(c) 9 km/hr
(d) 5.6 km/hr

(a) 2.5 km/hr
(b) 1.5 km/hr
(c) 3.5 km/hr
(d) 4.5 km/hr
Q11. A boat takes half time in moving a certain distance downstream than upstream. The ratio of the speed of the boat in still water and that of the current is
(a) 2 : 1
(b) 4 : 3
(c) 1 : 2
(d) 3 : 1
Q12. A man rows upstream 36 km and downstream 48 km taking 6 hours each time. The speed of the current is:
(a) 0.5 km/hr
(b) 1 km/hr
(c) 2 km/hr
(d) 1.5 km/hr

(a) 1 hour 277/13 minutes
(b) 1 hours 247/13 minutes
(c) 1 hours 257/13 minutes
(d) 1 hours 267/13 minutes
Q14. A man rows to a place 60 km distance and back in 13 hours 30 minutes. He finds that he can row 5 km with the stream in the same time as he can row 4 km against the stream. Find the rate of the stream.
(a) 8 km/hr
(b) ½ km/hr
(c) 10 km/hr
(d) 1 km/hr
Q15. A motor boat covers a certain distance downstream in a river in 3 hours. It covers the same distance upstream in 3.5 hours. If the speed of the water is 1.5 km/hr, then the speed of the boat in still water is:
(a) 17 km/hr
(b) 17.5 km/hr
(c) 19.5 km/hr
(d) 19 km/hr
