∙ 14y agoCall 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.

That depends on the speed. After deciding how fast you will travel, divide the distance by the speed to get the time.That depends on the speed.

When a baseball is hit, the distance it will travel depends on its speed.
what is the speed of pedrothat does it take to travel 672km at 2hrs
The mean speed of the flow of the Agulhas Current is estimated to be 0.5 to 1.4 miles per hour. The current is located in the southwest Indian Ocean.
it allowed the Mesopotamians to travel along the rivers allowing them to speed up all travel alongside our on the river
velocity
Not by our current understanding of physics or technology.
Most of the passenger river boat travels at 35 knots per hour.
The velocity of the boat relative to the shore is the vector sum of its velocity relative to the river and the velocity of the river current. In this case, it would be 4 km/h (boat's speed) + 5 km/h (current's speed), which equals 9 km/h.
To travel at the speed of light, you would need to have an infinite amount of energy, which is currently not possible with our current technology and understanding of physics. Additionally, as per the theory of relativity, an object with mass cannot reach the speed of light.
Arc length, current (amperage,) travel speed, work angle, travel angle.
With current technology, it is not possible to even come anywhere close to the speed of light. For example, traveling at 1/10 the speed of light is still science fiction. On the other hand, for anything that does NOT travel at the speed of light, it is impossible to actually attain the speed of light. In theory you might get close. There are some particles, such as photons and the hypothetical gravitons, which ONLY travel at the speed of light.
No, the water travels at different speeds depending on the terrain. That's why you have some sections of a river called "rapids."
Electricity and water are often compared to help explain how electricity works. Voltage is like the speed of water in a river, and electrical current is like the amount of water in the river. Resistance can be compared to the physical width of the river. Power is voltage times current, or the speed of the water times the amount of water. Electricity is usually most dangerous when it is available at high power - similar to a huge, fast moving river.

Humans are not capable of running that fast, no, but they can travel that fast using a vehicle. The current air speed record is Mach 6.7.
