Question 1

A boat travels at 22 km/h in still water. The stream flows at 4 km/h. How long will it take to go 73 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 22 - 4 = 18 km/h
2. Time = Distance / Speed = 73 / 18 = 4.1 hours

Question 2

A boat travels 49 km downstream in 1.8 hours and upstream in 2.9 hours. The stream speed is 5 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 5 km/h
2. Downstream: 49/(x + 5) = 1.8
3. Upstream: 49/(x - 5) = 2.9
4. Solving gives x = 22 km/h

Question 3

A boat travels at 19 km/h in still water. The stream flows at 3 km/h. How long will it take to go 55 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 19 - 3 = 16 km/h
2. Time = Distance / Speed = 55 / 16 = 3.4 hours

Question 4

A boat travels at 16 km/h in still water. The stream flows at 7 km/h. How long will it take to go 46 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 16 + 7 = 23 km/h
2. Time = Distance / Speed = 46 / 23 = 2.0 hours

Question 5

A boat travels at 16 km/h in still water. The stream flows at 5 km/h. How long will it take to go 44 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 16 + 5 = 21 km/h
2. Time = Distance / Speed = 44 / 21 = 2.1 hours

Question 6

A boat travels at 22 km/h in still water. The stream flows at 3 km/h. How long will it take to go 56 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 22 + 3 = 25 km/h
2. Time = Distance / Speed = 56 / 25 = 2.2 hours

Question 7

A boat travels 34 km downstream in 1.8 hours and upstream in 2.6 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: 34/(x + 3) = 1.8
3. Upstream: 34/(x - 3) = 2.6
4. Solving gives x = 16 km/h

Question 8

A boat travels at 12 km/h in still water. Stream speed is 8 km/h. What is the difference between upstream and downstream time for 53 km?
Step-by-step:
1. Downstream speed = 20 km/h, Time = 2.6 hours
2. Upstream speed = 4 km/h, Time = 13.2 hours
3. Difference = 13.2 - 2.6 = 10.6 hours

Question 9

A boat travels at 25 km/h in still water. Stream speed is 6 km/h. What is the difference between upstream and downstream time for 44 km?
Step-by-step:
1. Downstream speed = 31 km/h, Time = 1.4 hours
2. Upstream speed = 19 km/h, Time = 2.3 hours
3. Difference = 2.3 - 1.4 = 0.9 hours

Question 10

A boat travels at 18 km/h in still water. The stream flows at 6 km/h. How long will it take to go 58 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 18 - 6 = 12 km/h
2. Time = Distance / Speed = 58 / 12 = 4.8 hours

Question 11

A boat travels at 10 km/h in still water. The stream flows at 7 km/h. How long will it take to go 44 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 10 - 7 = 3 km/h
2. Time = Distance / Speed = 44 / 3 = 14.7 hours

Question 12

A boat travels 71 km downstream in 2.3 hours and upstream in 4.2 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: 71/(x + 7) = 2.3
3. Upstream: 71/(x - 7) = 4.2
4. Solving gives x = 24 km/h

Question 13

A boat travels at 23 km/h in still water. The stream flows at 6 km/h. How long will it take to go 38 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 23 - 6 = 17 km/h
2. Time = Distance / Speed = 38 / 17 = 2.2 hours

Question 14

A boat travels 51 km downstream in 2.0 hours and upstream in 5.1 hours. The stream speed is 8 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 8 km/h
2. Downstream: 51/(x + 8) = 2.0
3. Upstream: 51/(x - 8) = 5.1
4. Solving gives x = 18 km/h

Question 15

A boat travels 41 km downstream in 1.5 hours and upstream in 2.2 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
