Question 1

A boat travels at 14 km/h in still water. The stream flows at 8 km/h. How long will it take to go 71 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 14 - 8 = 6 km/h
2. Time = Distance / Speed = 71 / 6 = 11.8 hours

Question 2

A boat travels at 16 km/h in still water. Stream speed is 7 km/h. What is the difference between upstream and downstream time for 34 km?
Step-by-step:
1. Downstream speed = 23 km/h, Time = 1.5 hours
2. Upstream speed = 9 km/h, Time = 3.8 hours
3. Difference = 3.8 - 1.5 = 2.3 hours

Question 3

A boat travels 70 km downstream in 3.5 hours and upstream in 8.8 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: 70/(x + 6) = 3.5
3. Upstream: 70/(x - 6) = 8.8
4. Solving gives x = 14 km/h

Question 4

A boat travels 54 km downstream in 2.0 hours and upstream in 4.9 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: 54/(x + 8) = 2.0
3. Upstream: 54/(x - 8) = 4.9
4. Solving gives x = 19 km/h

Question 5

A boat travels at 12 km/h in still water. The stream flows at 5 km/h. How long will it take to go 62 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 12 + 5 = 17 km/h
2. Time = Distance / Speed = 62 / 17 = 3.6 hours

Question 6

A boat travels at 24 km/h in still water. The stream flows at 4 km/h. How long will it take to go 34 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 24 - 4 = 20 km/h
2. Time = Distance / Speed = 34 / 20 = 1.7 hours

Question 7

A boat travels at 24 km/h in still water. The stream flows at 4 km/h. How long will it take to go 34 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 24 + 4 = 28 km/h
2. Time = Distance / Speed = 34 / 28 = 1.2 hours

Question 8

A boat travels 57 km downstream in 2.7 hours and upstream in 11.4 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: 57/(x + 8) = 2.7
3. Upstream: 57/(x - 8) = 11.4
4. Solving gives x = 13 km/h

Question 9

A boat travels at 13 km/h in still water. The stream flows at 5 km/h. How long will it take to go 56 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 13 - 5 = 8 km/h
2. Time = Distance / Speed = 56 / 8 = 7.0 hours

Question 10

A boat travels 32 km downstream in 1.1 hours and upstream in 2.5 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: 32/(x + 8) = 1.1
3. Upstream: 32/(x - 8) = 2.5
4. Solving gives x = 21 km/h

Question 11

A boat travels at 24 km/h in still water. The stream flows at 6 km/h. How long will it take to go 42 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 24 - 6 = 18 km/h
2. Time = Distance / Speed = 42 / 18 = 2.3 hours

Question 12

A boat travels 70 km downstream in 2.5 hours and upstream in 5.0 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: 70/(x + 7) = 2.5
3. Upstream: 70/(x - 7) = 5.0
4. Solving gives x = 21 km/h

Question 13

A boat travels at 10 km/h in still water. The stream flows at 6 km/h. How long will it take to go 40 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 10 + 6 = 16 km/h
2. Time = Distance / Speed = 40 / 16 = 2.5 hours
