Question

What is average speed?​

Answer 1

$\large{\mathtt{\red{\underbrace{\overbrace{\blue{\boxed{\boxed{\pink{«Answer»}}}}}}}}}$

The average speed of an object is an indication of the average rate at which it covers a particular distance. So, if a car's average speed is around 60 km/h, this means that the car's position would change by 60 km/h on the average. Average speed is certainly a rate.

Answer 2

$\huge\underline{\mathbb\red{❥︎A}\green{N}\mathbb\blue{S}\purple{W}\mathbb\orange{E}\pink{R}}\:$

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion.
