- A boat can cover 25 km upstream and 42 km downstream together in 7 hours. Also it can cover 30 km upstream and 63 km downstream together in 9 hours. What is the speed of the boat in still water?

A) 13 km/hr

B) 8 km/hr

C) 7 km/hr

D) 11 km/hr

E) 16 km/hr

- A man rows to a certain place and comes back, but by mistake he covers 1/3rd more distance while coming back. The total time for this journey is 10 hours. The ratio of speed of boat to that of stream is 2 : 1. If the difference between upstream and downstream speed is 12km/hr, then how much time will the man take to reach to starting point from his present position?

A) 35 minutes

B) 45 minutes

C) 60 minutes

D) 40 minutes

E) 55 minutes

- A man can row at a speed of 15 km/hr in still water to a certain upstream point and back to the starting point in a river which flows at 9 km/hr. Find his average speed for total journey.

A) 10.4 km/hr

B) 8.4 km/hr

C) 9.1 km/hr

D) 5.2 km/hr

E) 9.6 km/hr

- A boat takes 5 hours for travelling downstream from point A to point B and coming back to point C at 3/4th of total distance between A and B from point B. If the velocity of the stream is 3 kmph and the speed of the boat in still water is 9 kmph, what is the distance between A and B?

A) 24 km

B) 32 km

C) 27 km

D) 21 km

E) 34 km

- At its usual rowing rate, a boat can travel 18 km downstream in 4 hours less than it takes to travel the same distance upstream. But if he the usual rowing rate for his 28-km round trip was 2/3rd, the downstream 14 km would then take 12 hours less than the upstream 14 km. What is the speed of the current?

A) 1.5 km/h

B) 3 km/h

C) 2 km/h

D) 3.5 km/h

E) 4 km/hr

- A boat can row to a place 120 km away and come back in 25 hours. The time to row 24 km with the stream is same as the time to row 16 km against the stream. Find the speed of current.

A) 1.5 km/h

B) 3 km/h

C) 2 km/h

D) 3.5 km/h

E) 4 km/hr

- A boatman can row 4 Km along the stream in 20 minutes and return in 24 minutes. Find the speed of boatman in still water.

A) 10 km/hr

B) 8 km/hr

C) 15 km/hr

D) 12 km/hr

E) 11 km/hr

- A man can row a certain distance downstream in 3 hours and return the same distance in 9 hours. If the speed of current is 18 km/hr, find the speed of man in still water.

A) 47 km/hr

B) 48 km/hr

C) 42 km/hr

D) 50 km/hr

E) 36 km/hr

- Four times the downstream speed is 8 more than 15 times the upstream speed. If difference between downstream and upstream speed is 24 km/hr, then what is the ratio of speed in still water to the speed of the current?

A) 9 : 2

B) 5 : 3

C) 7 : 1

D) 4 : 1

E) 7 : 3

- A boat can cover 14 km upstream and 21 km downstream together in 3 hours. Also it can cover 21 km upstream and 42 km downstream together in 5 hours. What is the speed of current?

A) 13 km/hr

B) 8 km/hr

C) 7 km/hr

D) 11 km/hr

E) 16 km/hr
