Question 1

A boat travels at 21 km/h in still water. The stream flows at 4 km/h. How long will it take to go 73 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 21 + 4 = 25 km/h
2. Time = Distance / Speed = 73 / 25 = 2.9 hours

Question 2

A boat travels at 18 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 = 18 - 8 = 10 km/h
2. Time = Distance / Speed = 71 / 10 = 7.1 hours

Question 3

A boat travels at 17 km/h in still water. The stream flows at 3 km/h. How long will it take to go 37 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 17 + 3 = 20 km/h
2. Time = Distance / Speed = 37 / 20 = 1.9 hours

Question 4

A boat travels at 25 km/h in still water. The stream flows at 8 km/h. How long will it take to go 73 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 25 - 8 = 17 km/h
2. Time = Distance / Speed = 73 / 17 = 4.3 hours

Question 5

A boat travels at 21 km/h in still water. The stream flows at 8 km/h. How long will it take to go 52 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 21 + 8 = 29 km/h
2. Time = Distance / Speed = 52 / 29 = 1.8 hours

Question 6

A boat travels at 23 km/h in still water. The stream flows at 6 km/h. How long will it take to go 79 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 23 + 6 = 29 km/h
2. Time = Distance / Speed = 79 / 29 = 2.7 hours

Question 7

A boat travels 42 km downstream in 2.1 hours and upstream in 7.0 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: 42/(x + 7) = 2.1
3. Upstream: 42/(x - 7) = 7.0
4. Solving gives x = 13 km/h

Question 8

A boat travels at 18 km/h in still water. Stream speed is 3 km/h. What is the difference between upstream and downstream time for 33 km?
Step-by-step:
1. Downstream speed = 21 km/h, Time = 1.6 hours
2. Upstream speed = 15 km/h, Time = 2.2 hours
3. Difference = 2.2 - 1.6 = 0.6 hours

Question 9

A boat travels at 18 km/h in still water. The stream flows at 6 km/h. How long will it take to go 60 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 18 - 6 = 12 km/h
2. Time = Distance / Speed = 60 / 12 = 5.0 hours

Question 10

A boat travels at 21 km/h in still water. The stream flows at 5 km/h. How long will it take to go 66 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 21 - 5 = 16 km/h
2. Time = Distance / Speed = 66 / 16 = 4.1 hours

Question 11

A boat travels at 23 km/h in still water. The stream flows at 6 km/h. How long will it take to go 49 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 23 - 6 = 17 km/h
2. Time = Distance / Speed = 49 / 17 = 2.9 hours

Question 12

A boat travels at 18 km/h in still water. The stream flows at 8 km/h. How long will it take to go 67 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 18 + 8 = 26 km/h
2. Time = Distance / Speed = 67 / 26 = 2.6 hours

Question 13

A boat travels at 20 km/h in still water. The stream flows at 8 km/h. How long will it take to go 72 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 20 - 8 = 12 km/h
2. Time = Distance / Speed = 72 / 12 = 6.0 hours

A boat travels at 25 km/h in still water. The stream flows at 6 km/h. How long will it take to go 64 km downstream?
Step-by-step:
1. Downstream speed = Boat speed + Stream speed = 25 + 6 = 31 km/h
2. Time = Distance / Speed = 64 / 31 = 2.1 hours

Question 15

A boat travels at 13 km/h in still water. The stream flows at 7 km/h. How long will it take to go 62 km downstream?
Step-by-step:

2. Time = Distance / Speed = 62 / 20 = 3.1 hours

Question 16

A boat travels at 16 km/h in still water. The stream flows at 8 km/h. How long will it take to go 33 km upstream?
Step-by-step:
1. Upstream speed = Boat speed - Stream speed = 16 - 8 = 8 km/h
