Question 1

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 52 km?
Step-by-step:
1. Downstream speed = 22 km/h, Time = 2.4 hours
2. Upstream speed = 16 km/h, Time = 3.2 hours
3. Difference = 3.2 - 2.4 = 0.8 hours

Question 2

Step-by-step:
1. Downstream speed = 26 km/h, Time = 1.2 hours
2. Upstream speed = 16 km/h, Time = 1.9 hours
3. Difference = 1.9 - 1.2 = 0.7 hours

Question 3

A boat travels at 19 km/h in still water. The stream flows at 5 km/h. How long will it take to go 69 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 19 + 5 = 24 km/h
2. Time = Distance / Speed = 69 / 24 = 2.9 hours

Question 4

A boat travels at 18 km/h in still water. The stream flows at 3 km/h. How long will it take to go 40 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 18 - 3 = 15 km/h
2. Time = Distance / Speed = 40 / 15 = 2.7 hours

Question 5

A boat travels at 17 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 = 21 km/h, Time = 3.8 hours
2. Upstream speed = 13 km/h, Time = 6.1 hours
3. Difference = 6.1 - 3.8 = 2.3 hours

Question 6

A boat travels 54 km downstream in 2.3 hours and upstream in 3.6 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: 54/(x + 4) = 2.3
3. Upstream: 54/(x - 4) = 3.6
4. Solving gives x = 19 km/h

Question 7

A boat travels 59 km downstream in 2.1 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: 59/(x + 7) = 2.1
3. Upstream: 59/(x - 7) = 4.2
4. Solving gives x = 21 km/h

Question 8

A boat travels 33 km downstream in 1.1 hours and upstream in 2.4 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: 33/(x + 8) = 1.1
3. Upstream: 33/(x - 8) = 2.4
4. Solving gives x = 22 km/h

Question 9

A boat travels 62 km downstream in 3.0 hours and upstream in 12.4 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: 62/(x + 8) = 3.0
3. Upstream: 62/(x - 8) = 12.4
4. Solving gives x = 13 km/h

Question 10

A boat travels at 16 km/h in still water. The stream flows at 8 km/h. How long will it take to go 38 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 16 + 8 = 24 km/h
2. Time = Distance / Speed = 38 / 24 = 1.6 hours

Question 11

A boat travels 35 km downstream in 1.2 hours and upstream in 2.2 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: 35/(x + 6) = 1.2
3. Upstream: 35/(x - 6) = 2.2
4. Solving gives x = 22 km/h

Question 12

A boat travels at 21 km/h in still water. Stream speed is 5 km/h. What is the difference between upstream and downstream time for 64 km?
Step-by-step:
1. Downstream speed = 26 km/h, Time = 2.5 hours
2. Upstream speed = 16 km/h, Time = 4.0 hours
3. Difference = 4.0 - 2.5 = 1.5 hours

Question 13

A boat travels at 12 km/h in still water. The stream flows at 8 km/h. How long will it take to go 58 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 12 + 8 = 20 km/h
2. Time = Distance / Speed = 58 / 20 = 2.9 hours

Question 14

A boat travels 61 km downstream in 2.2 hours and upstream in 3.0 hours. The stream speed is 4 km/h. Find the boat's speed in still water.
