Any unit of length divided by any unit of time is a unit of speed.
A few examples include . . .
-- meter per second
-- mile per hour
-- foot per minute
-- light-year per millenium
-- furlong per fortnight
-- smoot per week
-- knot (one knot is 1 nautical mile per hour)
Commonly used units are obtained by dividing a unit of length by a unit of time, for example, meters/second, or kilometers/hour. There are also speed units that don't explicitly relate to a length and a time, such as the "knot", or "fraction of the speed of light".
Answer #1:
The most common unit of speed is kilometer per hour in the UK,
and miles per our in the US. In the air and on water, it is measured
in knots.
==================================
Answer #2:
(any unit of length)/(any unit of time) is a perfectly good unit of speed. Then, tell the direction
of the length, and you have a velocity. Possible units of speed or velocity are miles per hour (symbol mi/h or mph; metres per second (symbol m s−1 or m/s), kilometers per hour (symbol km/h); ;
i think that it is hours but don't tell your teachers
no its not its m/s
m/s
The standard SI unit of speed is the m/s, metres per second. Speed = Distance/ Time
(Any unit of length) divided by (any unit of time) is a unit of speed.
Use any unit of length, divided by any unit of time. Km/h is commonly used for speeds of people, cars, and aircraft; but in science, m/s is used instead (that's the official SI unit).
distance divided by time
distance divided by speed equals to speed
Velocity is speed and its direction. The units of velocity are any unit of speed and any means of indicating a direction.
Speed is the magnitude of velocity, with units of distance divided by time. An important distinction is that speed is a scalar and velocity is a vector. Consequently, speed (unlike velocity) does not have a direction.
The difference between an object's speed and an object's velocity is that the object's speed is how fast it is going, and the object's velocity is how many units of speed the object has traveled.
For a start, acceleration doesn't even have the same units as velocity: acceleration is a velocity divided by time, so while speed or velocity have units of [distance]/[time], acceleration has units of [distance]/[time squared]
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
Velocity is speed and its direction. The units of velocity are any unit of speed and any means of indicating a direction.
Velocity is speed, plus an indication of direction. To indicate a velocity, you can indicate a speed (this will logically use units of speed), and a direction.
No, not at all possible. But constant speed with changing velocity is possible.
Speed is the magnitude of velocity, with units of distance divided by time. An important distinction is that speed is a scalar and velocity is a vector. Consequently, speed (unlike velocity) does not have a direction.
No because velocity defined as speed in a given direction so if speed is 0 then velocity must also be 0
The units are the same (metres per second) except that the velocity also has the direction of motion associated with it.

Negative speed isn't possible, but negative velocity is.
No, it isn't possible. Velocity specifies both speed and direction; if velocity doesn't change, that means that neither the speed nor the direction change.
Velocity is a vector quantity. That means it has direction and magnitude. Speed is a scalar quantity, it only has magnitude. It is possible to have constant speed and constant velocity but it is also possible to have constant speed but changing velocity if the object is changing direction.
because they measure different aspects of the same thing, velocity also has direction but speed lacks direction. otherwise they are the same.
