Question

what is speed...

...​

Answer 1

Speed:-

Rate of change of motion is called speed or distance covered by a moving body per unit time is called speed.

Speed = Distance/Time

S.I unit :- m/s

More:-

Velocity:-

The rate of change of motion of a specified direction is called velocity or the rate of change of displacement is called velocity.

Velocity = Displacement/Time

S.I unit :- m/s

Distance:-

The length of the path travelled by the body in a certain interval of time is called distance.

Scalar Quantity ✓

S.I unit :- m

Displacement:-

The shortest distance travelled between the initial position and the final position of a body is called displacement.

Vector Quantity ✓

S.I unit :- m

Time:-

The interval between two event is called time.

S.I unit :- s

Answer 2

Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.
