Correct answer gives you +4 while wrong ones give you -1.

A Boat going upstream takes 8 hours 24 minutes to cover a certain distance, while it takes 5 hours to cover 5/7 of the same distance running downstream. Then what is the ratio of the speed of boat to speed of water current?*

11:1

11:6

11:5

6:5

A Boat takes total 16 hours for traveling downstream from point A to point B and coming back point C which is somewhere between A and B. If the speed of the Boat in Still water is 9 Km/hr and rate of stream is 6 Km/hr, then what is the distance between A and C?*

30 km

60 km

90 km

Cannot be determined

The speed of Boat in Still water is 40 Km/hr and speed of the stream is 20 Km/hr. The distance between Point A and Point B is 480 Km. The boat started traveling downstream from A to B, in the midway, it is powered by an Engine due to which speed of the Boat increased. Now Boat reached Point B and started back to point A with help of the same engine. It took 19 hours for the entire journey. Then with the help of the engine, the speed of the boat increased by how many Km/hr?*

10 km/hr

20 km/hr

15 km/hr

25 km/hr

A Boat takes total 10 hours for traveling downstream from point A to point B and coming back point C which is somewhere between A and B. The speed of the Boat in Still water is 9 Km/hr and rate of Stream is 3 Km/hr, then what is the distance between A and B if the ratio of distance between A to C and distance between B to C is 2:1?*

54 km

66 km

72 km

88 km

Speeds of Boat A and B in still water are in the ratio of 3:2 Rate of current is 10 Km/hr. Both Boats started from Point P to point Q downstream at the same time. After Boat B reaching Point Q, in return journey, it is powered by engine due to which the speed of the boat in still water is increased by 70%, while retuned Boat A returned to Point Q as usual. Both the boats returned back to point P at the same time. Then what is the speed of Boat A?*

20 km/hr

30 km/hr

40 km/hr

50 km/hr

A Boat took 8 hours less to travel a distance downstream than to travel the same distance upstream. If the speed of a boat in still water is 9 Km/hr and speed of a stream is 3 Km/hr. In total how much distance traveled by boat?*

192 km

164 km

144 km

96 km

A boat covers a certain distance downstream in 1 hour, while it comes back in 1¹/₂ hours. If the speed of the stream be 3 kmph, what is the speed of the boat in still water?*

15 kmph

14 kmph

13 kmph

12 kmph

A man rows to a place 48 km distant and come back in 14 hours. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is:*

1 kmph

1.5 kmph

2 kmph

2.5 kmph

A boat covers 24 km upstream and 36 km downstream in 6 hours, while it covers 36 km upstream and 24 km downstream in 6¹/₂ hours. The speed of the current is?*

1 kmph

1.5 kmph

2 kmph

2.5 kmph

A boat while dowenstream in a reiver converd a distance of 50 miles at an average speed of 60 miles per hour. While returning , because of the water resistance , it took 1 hour 15 minutes to cover the same distance What was the average speed during the whole journey?*

55 mph

50 mph

48 mph

40 mph

Page 3/3Boats & Streams Complex

The speed of a boat downstream is 15 km/hr and the speed of current is 3 km/hr. Find the total time taken by the boat to cover 15 km upstream and 15 km downstream.*

2 hours 42 minutes

2 hours 40 minutes

2 hours 30 minutes

2 hours 10 minutes

A man row to a place 48 km distant and back on 14 hours text. He finds that he can row 4 km with the stream in the same time as 3 km against the stream. The rate of the stream is?*

1 km/hr

1.5 km/hr

1.8 km/hr

3.5 km/hr

A man takes 2.2 times as long to row a distance upstream as to row the same distance downstream. If he can row 55 km downstream in 2 hour 30 minutes, what is the speed of the boat in the still water?*

40 km/hr

24 km/hr

16 km/hr

8 km/hr

A boat can tarvel 36 km upstream in 5 hours. If the speed of the stream is 2.4 kmph, how much time will the boat take to cover a distance of 78 km downstream?(in hours)*

6.5

5.5

On a river , Q is the mid – point between two points P and R on the same bank of the river. A boat can go from P to Q and back in 12 hours, and from P to R in 16 hours 40 minutes. How long would it take to go from R to P?*

24/7 hr

5 hr

20/3 hr

8/3 hr
