If a river current is 8.0 miles per second and a boat is traveling 10.0 miles per second upstream what is the boat's speed relative to the riverbank?

2 miles per second upstream relative to the river bank.
Note: This is quite a scenario, even for experienced rapids-shooters.
That river is flowing at 28,800 miles per hour, and the guy is paddling
his kayak through the water at 36,000 miles per hour. The whole scene
is definitely poised to launch itself into solar orbit.

8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.
What is the rate of the current if Jim's motorboat travels downstream at the rate of 15km per hour and going upstream it travels at 7km per hour?
The current flows at 4 kph.The boat motors at 11 kph.
In still water a boat can travel four times as fast as the current in the river A trip up the river and back which totaled 150 km took 8h Find the speed of the current?
Call the unknown speed of the current c and the speed of the boat in still water b. When travelling upstream, the net speed of the boat will be b - c and when travelling downstream the net speed of the boat will be b + c. Since b = 4c, the speed upstream will be 3c. The distance upstream is one-half the total travelling distance of 150 km or 75 kilometers. Distance travelled = speed X time at speed, so that upstream time = 75/3c, downstream time = 75/5c, and the sum of these is the total time stated to be 8 hours. Thus 75/3c + 75/5c = 8. Multiplying both sides by 15c yields 75(5 +3) = 120c, or c = (8 X 75)/120 = 5 kilometers per hour.
How much time is 983 miles?
In order to determine how much time it takes to travel 983 miles you need to know your current speed. Traveling at 30 mph, it would take much longer than traveling at 60 mph.
8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
If a river current is 8.0 meters per second and a boat is traveling 10.0 meters per second upstream what is the boat's speed relative to the riverbank?
ans is = 10 - 8 = 2 m/s (upstream)
How do you ferry a current?
In order to ferry a current you need to point your boat an an angle across the river and pointing upstream. The stronger the current the more you will have to point upstream. You simply paddle at this angle until you reach the other side. It also can help if you lift your upstream knee slightly so that the water doesn't catch your upstream edge.
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.
What does it mean swimming up stream?
Swimming upstream is to do something the hard way. It is more difficult to swim against the current. Salmon swim upstream in order to spawn.
Why did the ferry boat have to go upstream before crossing the river?
if the boat turns toward the dock without going upstream, it will miss it's mark because the current is pushing the boat downstream.
If a fishing boat travels 15mph in still waters how long will it take it to travel 30 miles upstream with a current of 3?
The boat travels past the water around it at 15 mph.If the water is moving past the riverbank at 3 mph, then the boat is moving past the riverbankat (15 - 3) = 12 mph.At 12 mph, it takes (30/12) = 2-1/2 hours (2hr 30min) to travel 30 miles up the riverbank.Coming back, the boat's speed past the riverbank will be (15+3) = 18 mph.It will take (30/18) = 1-2/3 hours (1hr 40min) to travel 30 miles down the riverbank.
Can earth fault current go up passing through the downstream panel and directly cause a trip at the upstream panel which have higher set point of earth fault protection?
If the fault is a direct short to ground, the fault current can be high enough to trip the upstream protection.
Does an electric current traveling through a wire generate a magnetic field?
Yes, an electric current traveling through a wire generates a magnetic field. There is no way that it cannot do this.
Is current absolute or relative quantity?
current is relative because it is measured with respect to time. actually it is the rate of flow of charges with respect to time.when we measured current we measured charges with respect to time. that why it is relative quantity john ahem senior professor at Cambridge university
What is the difference between absolute path name and relative path name in Unix?
Absolute path: Path from root directory (it is the same place, wherever the current path is) Relative path: Relative to the current path.
What is the current water level of the Banana River relative to normal pool level?
Current as of when?
