Question 1

A boat travels at 23 km/h in still water. Stream speed is 4 km/h. What is the difference between upstream and downstream time for 79 km?
Step-by-step:
1. Downstream speed = 27 km/h, Time = 2.9 hours
2. Upstream speed = 19 km/h, Time = 4.2 hours
3. Difference = 4.2 - 2.9 = 1.3 hours

Question 2

A boat travels 31 km downstream in 1.2 hours and upstream in 1.7 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: 31/(x + 4) = 1.2
3. Upstream: 31/(x - 4) = 1.7
4. Solving gives x = 22 km/h

Question 3

A boat travels at 15 km/h in still water. Stream speed is 5 km/h. What is the difference between upstream and downstream time for 78 km?
Step-by-step:
1. Downstream speed = 20 km/h, Time = 3.9 hours
2. Upstream speed = 10 km/h, Time = 7.8 hours
3. Difference = 7.8 - 3.9 = 3.9 hours

Question 4

A boat travels at 23 km/h in still water. The stream flows at 5 km/h. How long will it take to go 79 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 23 + 5 = 28 km/h
2. Time = Distance / Speed = 79 / 28 = 2.8 hours

Question 5

A boat travels at 14 km/h in still water. The stream flows at 8 km/h. How long will it take to go 78 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 14 - 8 = 6 km/h
2. Time = Distance / Speed = 78 / 6 = 13.0 hours

Question 6

A boat travels 42 km downstream in 2.1 hours and upstream in 10.5 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: 42/(x + 8) = 2.1
3. Upstream: 42/(x - 8) = 10.5
4. Solving gives x = 12 km/h

Question 7

A boat travels at 22 km/h in still water. The stream flows at 6 km/h. How long will it take to go 41 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 22 + 6 = 28 km/h
2. Time = Distance / Speed = 41 / 28 = 1.5 hours

Question 8

A boat travels 38 km downstream in 2.2 hours and upstream in 7.6 hours. The stream speed is 6 km/h. Find the boat's speed in still water.
Step-by-step:
1. Let boat speed = x km/h, stream speed = 6 km/h
2. Downstream: 38/(x + 6) = 2.2
3. Upstream: 38/(x - 6) = 7.6
4. Solving gives x = 11 km/h

Question 9

A boat travels at 14 km/h in still water. The stream flows at 6 km/h. How long will it take to go 53 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 14 + 6 = 20 km/h
2. Time = Distance / Speed = 53 / 20 = 2.6 hours

Question 10

A boat travels at 19 km/h in still water. The stream flows at 4 km/h. How long will it take to go 32 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 19 + 4 = 23 km/h
2. Time = Distance / Speed = 32 / 23 = 1.4 hours

Question 11

A boat travels 73 km downstream in 4.1 hours and upstream in 9.1 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: 73/(x + 5) = 4.1
3. Upstream: 73/(x - 5) = 9.1
4. Solving gives x = 13 km/h

Question 12

A boat travels at 10 km/h in still water. The stream flows at 7 km/h. How long will it take to go 41 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 10 + 7 = 17 km/h
2. Time = Distance / Speed = 41 / 17 = 2.4 hours

Question 13

A boat travels at 22 km/h in still water. The stream flows at 7 km/h. How long will it take to go 53 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 22 - 7 = 15 km/h
2. Time = Distance / Speed = 53 / 15 = 3.5 hours

Question 14

A boat travels at 10 km/h in still water. The stream flows at 7 km/h. How long will it take to go 57 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 10 + 7 = 17 km/h
2. Time = Distance / Speed = 57 / 17 = 3.4 hours

Question 15

A boat travels at 22 km/h in still water. The stream flows at 5 km/h. How long will it take to go 79 km downstream?
