How do you find the speed of a boat in still water and the speed of the current?
Upstream and Downstream – Formula
- Upstream = (u−v) km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Downstream = (u+v)Km/hr, where “u” is the speed of the boat in still water and “v” is the speed of the stream.
- Speed of Boat in Still Water = ½ (Downstream Speed + Upstream Speed)
How do you find distance in a word problem?
We can use the distance = rate ⋅ time formula to find the distance Lee traveled. The formula d = rt looks like this when we plug in the numbers from the problem. The unknown distance is represented with the variable d. To find d, all we have to do is multiply 65 and 2.5.
How do you solve mph math problems?
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour.
How do you solve for distance example?
When solving these problems, use the relationship rate (speed or velocity) times time equals distance. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h)(4h) = 120 km.
How do you find the speed of water current?
Answer
- The distance going upstream and downstream is the same.
- Time going upstream is 3 hours.
- Time going downstream is 2 hours.
- Speed of the boat (r) is 5 miles per hour.
- Distance (d) = rate (r) X time (t)
What is speed of boat in still water?
And, the direction against the stream is called upstream. If the speed of a boat in still water is u km/hr and the speed of the stream is v km/hr, then: Speed downstream = (u + v) km/hr. Speed upstream = (u – v) km/hr….Exercise :: Boats and Streams – Important Formulas.
| Rate of stream = | 1 | (a – b) km/hr. |
|---|---|---|

How do you find the speed with given distance and time?
The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
How do you work out speed in mph?
Speed = Distance / Time If distance was measured in miles and time in hours, then output will be in miles per hour (mph, mi/h), and so on for km/h, m/s, etc.
How many hours can you paddle in a day?
One group of people may paddle 5 hours every day for 10 days, 10 hours each day for 5 days or 20 on Day 1, rest on Day 2 and Day 3, paddle 10 on Day 4, Day 5 and Day 6. It really just depends upon what the group wants to do. It’s best to determine this before you’re out in the wilderness.
What’s the average kayak speed for a mile?
In other words, you can kayak a mile in roughly 20-30 minutes under average circumstances. This speed can be expected to be maintained for several hours, similar to that of a brisk walking pace. A beginner level kayaker should expect to be a bit slower than this, likely around 2-2.5 knots.
What are the factors that affect paddling speed?
On moving water your average paddling speed can be both helped and hindered by current and wind speed. Whether these factors are favorable or not depends a lot on speed and direction. Either way, they impact your performance and time.
How many miles can you Canoe in a day?
How many miles can you canoe in a day? You could canoe 20 miles in a day, taking into account our example speed and mileage of 3.5 hours to paddle 10 miles. That would account for 7 hours of straight paddling plus a few breaks in between, about an entire day.
