# Aptitude  Boats and Streams  Practice Q&A

1. The speed of a boat in still water is 15 km/hr and the rate of current is 3 km/hr. The distance travelled downstream in 24 minutes is

 3.6 km 2.4 km 3.2 km 7.2 km

2. A man can row three-quarters of a kilometre against the stream in 11$\dfrac{1}{4}$ minutes and down the stream in 7$\dfrac{1}{2}$ minutes. The speed in km/hr of the man in still water is:

 2 3 4 5

3. A boat goes 8 km upstream in 24 minutes. The speed of stream is 4 km/hr. The speed of boat in still water is:

 25 km/hr 26 km/hr 22 km/hr 24 km/hr

4. A mans speed with the current is 15 km/hr and the speed of the current is 2.5 km/hr. The mans speed against the current is:

 8.5 km/hr 9 km/hr 10 km/hr 12.5 km/hr

5. The speed of a boat in still water is 8 kmph. If it can travel 1 km upstream in 1 hr, what time it would take to travel the same distance downstream?

 1 minute 2 minutes 3 minutes 4 minutes

6. Speed of a boat in standing water is 14 kmph and the speed of the stream is 1.2 kmph. A man rows to a place at a distance of 4864 km and comes back to the starting point. The total time taken by him is:

 700 hours 350 hours 1400 hours 1010 hours

7. A boat can travel with a speed of 22 km/hr in still water. If the speed of the stream is 5 km/hr, find the time taken by the boat to go 54 km downstream

 5 hours 4 hours 3 hours 2 hours

8. A boat running downstream covers a distance of 22 km in 4 hours while for covering the same distance upstream, it takes 5 hours. What is the speed of the boat in still water?

 5 kmph 4.95 kmph 4.75 kmph 4.65 kmph

9. A boat running upstream takes 8 hours 48 minutes to cover a certain distance, while it takes 4 hours to cover the same distance running downstream. What is the ratio between the speed of the boat and speed of the water current respectively?

 2 : 1 3 : 2 8 : 3 Cannot be determined

10. In a river flowing at 2 km/hr, a boat travels 32 km upstream and then returns downstream to the starting point. If its speed in still water be 6 km/hr, find the total journey time.

 10 hours 12 hours 14 hours 16 hours
