Question

How does instantaneous speed differ from average speed?

Answer 1

$\huge \mathfrak{Answer : }$

Average speed is the mean speed of an object all over the journey, it is calculated by dividing the total distance covered by total time taken

$\boxed{avg. \: \: speed = \dfrac{total \: \: \: distance}{total \: \: time} }$

where as,

Instantaneous speed is the speed of an object at a particular instant of time. it is calculated at an instant by using minute values using differentiation (calculus).

i.e

$\boxed{instantaneous \: \: speed = \dfrac{ds}{dt} }$

Answer 2

Answer:

constant speed is where the speed is the same throughout and instantaneous speed is speed given at any moment and average speed is a total distance traveled divided by the amount of time it took to travel it.
