Knots are used to measure speed on ships or boats. The term comes from the way people measured the speed the boat was traveling. They did it by tying knots on a rope at regular intervals and would then throw the rope overboard, counting the number of knots that were pulled overboard in a certain amount of time.
A knot is not a measurement of distance, but of speed. One knot equals 1.15 miles per hour.
The unit used for measuring the speed of something in/on water
one knot is equal yo one . three miles on the ground
There are several equations that involve speed; the basic equation, that defines speed, is: speed = distance / time Which is often written as: distance = speed x time This assumes constant speed. For variable speed, the limit should be taken, resulting in: dv = ds/dt where v is the velocity, s is the position, and t is the time.
One knot is equivalent to 1 nautical mile per hour. A nautical mile is slightly larger than a standard mile, as it is 2000 yards, so 1 knot is slightly faster than 1 mph.
The whole goal with a knot is to create as much friction between each of the strings as possible. The greater the friction, the better the knot will hold. Silk string is very smooth as compared to the cotton string. So the friction produced when a cotton string is tied in a knot is greater than that when a knot tied with silk string. That is why a knot tied with cotton string will hold better than a knot tied with silk string.
If I drive away from my house at 8:00 in the morning and return at 6:00 PM that same evening with 50 more miles showing on the car, you know immediately that my average speed for the day was 5 mph. But you don't know a thing about how much of that time I was stopped, how much in motion, or what my speed was at any moment between 8 and 6, because there's no necessary relationship between instantaneous and average speed. I guess it's probably true to say that there has to be some instant during any period of time when the instantaneous speed must be equal to the average speed during the same period. That sounds like a nice theorem, and its proof ought to be good for some mathematical recreation, but it doesn't seem too useful.
1497 metres per second is the speed of sound in water at 25 degrees C. The speed in coffee will vary slightly with the density but will not be much different.
The 'knot' is a speed of 1.852 kilometers per hour.
time=distance x speed. to find speed, it is speed=distance/time distance=speed x time.
Well distance is pretty obvious. LAN's are usually in a uni campus, school or home. A WAN is over a much larger distance, i.e., a series of office buildings spread over a large area.
Distance traveled divided by how much time determines speed. Speed=distance/time
Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.Time = Distance/Speed = 100/2 = 50 seconds.
Speed is distance divided by time so pick the section you want to work out the average for, work out how much distance has been traveled in that section and divide it by how much time has passed for that section.
Not necessarily. The distance a car travels is determined by its speed and the time it spends traveling. If a car is traveling at a slower speed but for a longer period of time, it may not cover as much distance as a car traveling at a faster speed but for a shorter period of time. So, the longest time does not always correspond to the greatest distance traveled.
1 knot = 1.852 km/h
some may feel speed and velocity are same terms but both are diffrent,let seehow? Speed=distance travelled/time,that means it depents on how much distance you travelled,its a scalar quantity that means it dont depents on the direction velocity:it depents on diaplacement,ie;velocity=displacement/time,displacement is the measure of smallest distance between mean position and last,its a vecter quatity,so its value can be negetive,+ve,and may zero
That depends on the speed. Once you decide at what speed you will travel, divide the distance (in miles) by the speed (in miles per hours). The result will be in hours.That depends on the speed.

Just divide the distance by the speed.
That depends on how much the speed limit is.
