Question

difference between speed and average speed.

Answer 1

$\huge\bold\red{HELLO!}$

The difference between speed and average speed is that speed is a one time measurement of velocity while average speed is the median measurement of different speeds which basically is used simplify the varying speed to appear like a single speed only. ... The standard unit for speed in science is meters per second.

Answer 2

Explanation:

(Note, here speed means instantaneous speed, the concept which you'll clear in 11th std.)

Speed means the total distance covered in a unit time. For example 20km/h, it means the vehicle is traveling 20 kms in 1 hr. It is measured for a very very small distance.

Average speed is also the same but is measured from initial point to final point
