1. A boatman goes 2 km against the current of the stream in 1 hour and goes 1 km along the current in 10 minutes. How long will it take to go 5 km in stationary water? (3)
- 1. 40 minutes
- 2. 1 hour
- 3. 1 hr 15 min
- 4. 1 hr 30 min
2. Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. 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: (3)
- 1. 16 hours
- 2. 18 hours
- 3. 20 hours
- 4. 24 hours
3. A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is: (3)
- 1. 2 : 1
- 2. 3 : 1
- 3. 3 : 2
- 4. 4 : 3
4. 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: (2)
- 1. 1 km/hr
- 2. 1.5 km/hr
- 3. 2 km/hr
- 4. 2.5 km/hr
5. In one hour, a boat goes 11 km/hr along the stream and 5 km/hr against the stream. The speed of the boat in still water (in km/hr) is: (3)
- 1. 3 km/hr
- 2. 5 km/hr
- 3. 8 km/hr
- 4. 9 km/hr
