Correct Answer: (c) 8 hours 13 minutes 42 seconds
Solution:

2. The speed of a boat in still water is 30 km/h and the speed of the stream is 7.5 km/h. What is the time in hours taken by the boat in the stream to go from point A to B and then back to A covering a total distance of 90 km? [SSC MTS 05/09/2023 (1st Shift)]

Correct Answer: (a) 3.2
Solution:

3. A boat takes 20 hours for travelling downstream from point A to point B and comes back to a midpoint C between A and B. The speed of the stream is 5 km/h and the speed of the boat in still water is 10 km/h. Find the distance between A and B (in km). [SSC MTS 01/09/2023 (1st Shift)]

Correct Answer: (b) 120
Solution:

4. A boat takes 11 hours to travel a distance upstream and takes 5 hours to travel the same distance downstream. If the speed of the boat in still water is 2²⁄₉ m/sec, then the speed of the stream (in km/h) is [SSC CHSL 04/08/2023 (4th Shift)]

Correct Answer: (b) 3
Solution:

5. A boat can go 60 km downstream and 40 km upstream in 12 hours 30 minutes. It can go 84 km downstream and 63 km upstream in 18 hours 54 minutes. What is the speed (in km/h, to the nearest integer) of the boat in still water? [SSC CGL 20/07/2023 (1st shift)]

Correct Answer: (c) 9
Solution:

6. The speed of a boat upstream is 8 km/hr and the speed of stream is 4 km/hr. The boat covers a distance of x km upstream and x km downstream. If the total time taken by the boat is 9 hours, then what is the value of x?(in km) [SSC MTS 13/06/2023 (Evening)]

Correct Answer: (c) 48
Solution:

7. Time taken by boat to cover a distance of x km upstream is 3 hours more than the time taken by the boat to cover the same distance downstream. Speed of the boat upstream is 8 km/hr. Which of the following statement(s) is/are correct? [SSC MTS 12/05/2023 (Afternoon)]

I. If the value of x is 48 km, then the speed of the boat in downstream is 16 km/hr.
II. If the speed of boat in downstream is 12 km/hr, then the value of x is 48 km.

Correct Answer: (c) Only I
Solution:

8. A man can swim at a speed of 14 km/hr in still water. If he takes twice as long to swim opposite the flow of the river than with the flow of the river, find the rate of stream. [SSC MTS 09/05/2023 (Evening)]

Correct Answer: (d) 14/3km/hr
Solution:

9. The ratio of the speed of the boat in still water to the speed of the stream is 8 : 3 and the boat can travel 22 km downstream in 24 minutes. Then, how much time will the boat take to cover 50 km upstream? [SSC CHSL 13/03/2023 (2nd Shift)]

Correct Answer: (d) 2 hrs
Solution:

10. A man can row a distance of 8 km downstream in a certain time and can row 6 km upstream in the same time. If he rows 24 km upstream and the same 3 distance downstream in 1¾ hours, then the speed (in km/h) of the current is: [SSC CGL 17/8/2021 (Evening)]

Correct Answer: (a) 4
Solution:
