Total Questions: 27

21. A man can row 5 km/h in still water. If the speed of the current is 2.5 km/h, it takes 4 hours more in upstream than in the downstream for the same distance. The distance is : [SSC CHSL 24/05/2022 (Afternoon)]

Correct Answer: (b) 15 km
Solution:

22. A motorboat whose speed is 20 km/h in still water takes 30 minutes more to go 24 km upstream than to cover the same distance downstream. If the speed of the boat in still water is increased by 2 km/h, then how much time will it take to go 39 km downstream and 30 km upstream? [SSC CGL 11/04/2022 (Morning)]

Correct Answer: (b) 3 hrs 10 m
Solution:

23. A boat can cover a distance of 56 km downstream in 3.5 hours. The ratio of the boat in still water and the speed of the stream is 3:1. How much time will it take to cover a distance of 41.6 km downstream? [SSC CGL 18/04/2022 (Morning)]

Correct Answer: (c) 2.6
Solution:

24. A boat sails downstream from a point P to point Q, which is 24 km away from P, and then returns to P. If the actual speed of the boat (in still water) is 6 km/h, the entire trip from P to Q takes 3 hours less than that from Q to P. What should be the actual speed (in km/h) of the boat to sail from P to Q in 2 hours? [SSC MTS 08/10/2021 (Morning)]

Correct Answer: (c) 10
Solution:

25. A boat covers a round trip journey between two points A and B in a river in hours. If its speed in still water becomes 2 times, it would take (80/161)T hours for the same journey. Find the ratio of its speed in still water to the speed of the river. [SSC CGL 23/08/2021 (Morning)]

Correct Answer: (a) 11 : 1
Solution:

26. Ravi can row a boat in still water at the speed of 14 km/h. If a river is flowing at the speed of 2km/h and Ravi takes 3 hours to cover a certain distance upstream, then how much time will he take to cover the same distance. [SSC CHSL 06/08/2021 (Morning)]

Correct Answer: (c) 2h 15m
Solution:

27. The speed of a boat in still water is 15 km/h, and the speed of the current is 5 km/h, in how much time (in hours) will the boat travel a distance of 60 km upstream and the same distance downstream? [SSC CPO 25/11/2020 (Evening)]
