How do you solve a boat question?
What are the speed of the boat in still water and the speed of the stream? Solution : Speed of the boat in still water = 30 km/hr. Speed of the stream = 2 km/hr. Average speed-based questions: This is the simplest type, the speed of downstream and upstream will be mentioned and you have to find out the average speed.
Which is the correct formula for finding the speed of boat?
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. |
|---|---|---|
| 2 |
What is the formula for finding the speed of boat in still water?
Speed of the boat in still water = b (t2 + t1)/ (t2 – t1) km/hr. Example 3: A boat take 8 hours to cover a distance while traveling upstream, whereas while traveling downstream it takes 6 hours. If the speed of the current is 4 km/hr.
What is average speed of a boat?
Do boats go fast? With some popular boats average speed values
| Type of boat | Average speed | Top speed |
|---|---|---|
| Personal watercraft | 40 mph – 60 mph | 70 mph |
| Jon boats | 15 mph – 35 mph | 45 mph |
| Deck boats | 30 mph – 50 mph | 60 mph |
| Cruiser | 16 mph – 30 mph | 50 mph |
How do you calculate distance Travelled on a boat?
Below are all the variations of the distance, speed and time equation for calculating boating times.
- Distance = Speed x Time.
- Time = Distance/Speed.
- Speed = Distance/Time.
What is the speed of the boat in still water it takes 2 hours?
2. What is the speed of the boat in still water? I. It takes 2 hours to cover the distance between A and B downstream….II.
| Speed of the boat = | 1 | (8 + 12) km/hr = 10 km/hr. |
|---|---|---|
| 2 |
How do you measure the distance between a boat and stream?
Important Formulas – Boats and Streams speed of the stream =y = y km/hr. Let speed of a man in still water =x = x km/hr, speed of the stream =y = y km/hr, distance =d = d km.
What is speed of current in boat and stream?
In one hour, a boat goes 11 km/hr along the stream and 5 km/hr against the stream. The speed of the boat in still water (in km/hr) is: A. (11 + 5) kmph = 8 kmph….Exercise :: Boats and Streams – General Questions.
| A. | 2 hours |
|---|---|
| C. | 4 hours |
| D. | 5 hours |
What is the speed of boat in downstream?
The speed of boat downstream is equal to the sum of the speed of the boat in still water and speed of the stream .
What is the formula for boats and streams?
Here are some of the important boats and stream formulas: Upstream (u−v) km/hr Downstream (u+v)Km/hr Speed of Boat in Still Water ½ (Downstream Speed + Upstream Speed) Speed of Stream ½ (Downstream Speed – Upstream Speed) Average Speed of Boat { (Upstream Speed × Downstream Speed) /
How to calculate the speed of a boat in still water?
According to the formula, Speed of a boat in still water = ½ (DownstreamSpeed + UpstreamSpeed) Speed of boat in still water = ½ (13+7) = ½ × 20 = 10 km/hr Q 3.
How do you calculate distance between two points on a boat?
If it takes “t” hours for a boat to reach a point in still water and comes back to the same point then, the distance between the two points can be calculated by Distance = { (u2-v2) × t} / 2u, where “u” is the speed of the boat in still water and “v” is the speed of the stream
What is the speed of the boat in 1 hour?
In one hour, a boat goes 13 km/hr in the direction of the stream and 7 km/hr against the direction of the stream. What will be the speed of the boat in still water? Q 3. A woman can row upstream at 16 km/hr and downstream at 26 km/hr. What is the speed of the stream? Q 4.
