Boat and Stream

Total Questions: 50

11. X, Y are two points in a river. Points P and Q divide the straight line XY into three equal parts. The river flows along XY and the time taken by a boat to row from X to Q and from Y to Q are in the ratio 4:5. The ratio of the speed of the boat downstream to that of the river current is equal to: [SSC CGL 13/8/2021 (Morning)]

Solution:

16. The speed of a boat in still water is 8 km/h, while it takes 2 hours for the boat to cover a distance of 20 km downstream. What is the speed (in km/h) of the stream? [SSC MTS 09/10/2024 (Evening)]

1. (a) 2.5
2. (b) 1.75
3. (c) 2
4. (d) 1.5

Correct Answer: (c) 2

Solution:

17. A boat can travel at a speed of 28 km/h in still water. If the speed of the stream is 4 km/h, what is the average speed (in km/h) of the boat if it travels 192 km downstream, stops there for one hour and then returns to the starting point? [SSC MTS 14/10/2024 (Morning)]

1. (a) 25.6
2. (b) 24.8
3. (c) 36.5
4. (d) 28.5

Correct Answer: (a) 25.6

Solution:

18. A boat can travel at a speed of 42 km/hr in still water. If the speed of the stream is 3 km/hr, how much time (in hours and minutes) will be taken by the boat to go 157.5 km downstream, and then 78 km upstream ? [SSC MTS 21/10/2024 (Morning)]
