Question 1

A boat travels at 13 km/h in still water. The stream flows at 8 km/h. How long will it take to go 37 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 13 + 8 = 21 km/h
2. Time = Distance / Speed = 37 / 21 = 1.8 hours

Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 10 + 6 = 16 km/h
2. Time = Distance / Speed = 42 / 16 = 2.6 hours

Question 3

A boat travels at 16 km/h in still water. The stream flows at 5 km/h. How long will it take to go 36 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 16 - 5 = 11 km/h
2. Time = Distance / Speed = 36 / 11 = 3.3 hours

Question 4

A boat travels at 23 km/h in still water. The stream flows at 3 km/h. How long will it take to go 63 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 23 - 3 = 20 km/h
2. Time = Distance / Speed = 63 / 20 = 3.1 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 79 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 14 - 8 = 6 km/h
2. Time = Distance / Speed = 79 / 6 = 13.2 hours

Question 6

A boat travels 44 km downstream in 2.4 hours and upstream in 22.0 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: 44/(x + 8) = 2.4
3. Upstream: 44/(x - 8) = 22.0
4. Solving gives x = 10 km/h

Question 7

A boat travels at 17 km/h in still water. The stream flows at 7 km/h. How long will it take to go 77 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 17 + 7 = 24 km/h
2. Time = Distance / Speed = 77 / 24 = 3.2 hours

Question 8

A boat travels at 25 km/h in still water. The stream flows at 5 km/h. How long will it take to go 45 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 25 + 5 = 30 km/h
2. Time = Distance / Speed = 45 / 30 = 1.5 hours

Question 9

A boat travels at 11 km/h in still water. The stream flows at 6 km/h. How long will it take to go 62 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 11 + 6 = 17 km/h
2. Time = Distance / Speed = 62 / 17 = 3.6 hours

Question 10

A boat travels at 19 km/h in still water. Stream speed is 8 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 = 11 km/h, Time = 7.2 hours
3. Difference = 7.2 - 2.9 = 4.3 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 68 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 18 - 8 = 10 km/h
2. Time = Distance / Speed = 68 / 10 = 6.8 hours

Question 12

A boat travels 63 km downstream in 2.2 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: 63/(x + 7) = 2.2
3. Upstream: 63/(x - 7) = 4.2
4. Solving gives x = 22 km/h

Question 13

A boat travels at 24 km/h in still water. Stream speed is 5 km/h. What is the difference between upstream and downstream time for 36 km?
Step-by-step:
1. Downstream speed = 29 km/h, Time = 1.2 hours
2. Upstream speed = 19 km/h, Time = 1.9 hours
3. Difference = 1.9 - 1.2 = 0.7 hours

Question 14

A boat travels 59 km downstream in 3.7 hours and upstream in 5.9 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: 59/(x + 3) = 3.7
3. Upstream: 59/(x - 3) = 5.9
