Question 1

A boat travels 40 km downstream in 1.3 hours and upstream in 2.5 hours. The stream speed is 7 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 7 km/h
2. Downstream: 40/(x + 7) = 1.3
3. Upstream: 40/(x - 7) = 2.5
4. Solving gives x = 23 km/h

Step-by-step:
1. Downstream speed = 24 km/h, Time = 2.5 hours
2. Upstream speed = 18 km/h, Time = 3.3 hours
3. Difference = 3.3 - 2.5 = 0.8 hours

Question 3

A boat travels at 25 km/h in still water. The stream flows at 3 km/h. How long will it take to go 65 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 25 - 3 = 22 km/h
2. Time = Distance / Speed = 65 / 22 = 3.0 hours

Question 4

A boat travels at 22 km/h in still water. Stream speed is 6 km/h. What is the difference between upstream and downstream time for 75 km?
Step-by-step:
1. Downstream speed = 28 km/h, Time = 2.7 hours
2. Upstream speed = 16 km/h, Time = 4.7 hours
3. Difference = 4.7 - 2.7 = 2.0 hours

Question 5

A boat travels 53 km downstream in 2.9 hours and upstream in 5.3 hours. The stream speed is 4 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 4 km/h
2. Downstream: 53/(x + 4) = 2.9
3. Upstream: 53/(x - 4) = 5.3
4. Solving gives x = 14 km/h

Question 6

A boat travels at 19 km/h in still water. Stream speed is 3 km/h. What is the difference between upstream and downstream time for 71 km?
Step-by-step:
1. Downstream speed = 22 km/h, Time = 3.2 hours
2. Upstream speed = 16 km/h, Time = 4.4 hours
3. Difference = 4.4 - 3.2 = 1.2 hours

Question 7

A boat travels 77 km downstream in 5.9 hours and upstream in 11.0 hours. The stream speed is 3 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 3 km/h
2. Downstream: 77/(x + 3) = 5.9
3. Upstream: 77/(x - 3) = 11.0
4. Solving gives x = 10 km/h

Question 8

A boat travels at 17 km/h in still water. The stream flows at 7 km/h. How long will it take to go 64 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 17 - 7 = 10 km/h
2. Time = Distance / Speed = 64 / 10 = 6.4 hours

Question 9

A boat travels at 23 km/h in still water. The stream flows at 4 km/h. How long will it take to go 30 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 23 - 4 = 19 km/h
2. Time = Distance / Speed = 30 / 19 = 1.6 hours

Question 10

A boat travels at 19 km/h in still water. Stream speed is 7 km/h. What is the difference between upstream and downstream time for 71 km?
Step-by-step:
1. Downstream speed = 26 km/h, Time = 2.7 hours
2. Upstream speed = 12 km/h, Time = 5.9 hours
3. Difference = 5.9 - 2.7 = 3.2 hours

Question 11

A boat travels at 18 km/h in still water. The stream flows at 8 km/h. How long will it take to go 33 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 18 - 8 = 10 km/h
2. Time = Distance / Speed = 33 / 10 = 3.3 hours

Question 12

A boat travels at 13 km/h in still water. Stream speed is 7 km/h. What is the difference between upstream and downstream time for 51 km?
Step-by-step:
1. Downstream speed = 20 km/h, Time = 2.5 hours
2. Upstream speed = 6 km/h, Time = 8.5 hours
3. Difference = 8.5 - 2.5 = 6.0 hours
