About this subject

Boats and Streams

Correct options are highlighted when revealed.

1.A steamboat travels downstream from one harbor to another in 4 hours and returns upstream over the same distance in 5 hours. If the current's speed is 2 km/h, what is the distance between the two harbors?

2.A motorboat's speed is in the ratio 36:5 compared to the speed of the water current. If the boat takes 5 hours and 10 minutes to travel downstream, how long will it take to return upstream?

3.A boat travels at a speed of 5 km/h in still water. It covers 30 km upstream and then returns downstream to the starting point in a total of 4 hours and 30 minutes. What is the speed of the current?

4.A boat travels 30 km downstream in 2.5 hours and returns the same distance upstream in 3.75 hours. What is the boat's speed in still water?

5.A boat travels 24 km downstream in 10 hours, but takes 2 hours longer to cover the same distance upstream. What is the boat's speed in still water?

6.A boat travels 24 kilometers downstream in 4 hours, while it takes 6 hours to cover the same distance upstream. What is the speed of the boat in still water?

7.A person rows at a speed of 9 km/h in still water. He takes 4.5 hours to travel from point A to point B and back again. If the current flows at 1 km/h, what is the distance between points A and B?

8.A man rows a boat at 15 km/h in still water. If the river current flows at 3 km/h, how long will it take him to travel 60 meters downstream?

9.A boat travels downstream at 15.5 km/h and upstream at 8.5 km/h. What is the velocity of the current?

10.A person rows a boat at 18 km/h downstream and 10 km/h upstream. What are the speeds of the person in still water and the current, respectively?

11.A man rows 30 km downstream and 20 km upstream in a total of 4 hours. He also rows 45 km downstream and 40 km upstream in 7 hours. What is his speed in still water?

12.A man rows a boat such that the time taken to travel a certain distance upstream is double the time taken to cover the same distance downstream. If the boat's speed in still water is 42 km/h, what is the velocity of the current?

13.A man rows a boat at a speed of 20 km/h in still water. If the current flows at 6 km/h, how long will it take him to travel 60 km downstream?

14.A person rows a boat 85 km downstream and then 45 km upstream, taking 2.5 hours for each journey. What is the speed of the current?

15.A boat travels upstream at 60 km/h and downstream at 80 km/h. Calculate the boat's speed in still water and the velocity of the current.

16.A boat travels at 60 km/h in still water, and the current flows at 20 km/h. What are the boat's speeds when moving downstream and upstream?

17.A stream flows at a speed of 1 km/h. A motorboat travels 35 km upstream and then returns to the starting point, taking a total of 12 hours. What is the speed of the motorboat in still water?

18.A man rows a boat at 4.5 km/h in still water. He travels upstream against a river current flowing at 1.5 km/h to a certain point and then returns downstream to his starting position. What is his average speed for the entire trip?

19.A stream flows at 4 km/h. A boat travels 6 km downstream and then returns 6 km upstream, completing the round trip in 2 hours. What is the boat's speed in still water?

20.A man rows at a speed of 6 km/h in still water. If the river's current flows at 1.2 km/h, and it takes him exactly 1 hour to row to a destination and back, what is the total distance he covers during the trip?
