You have a contradiction in your question. Instantaneous acceleration is the acceleration at a certain moment in time. Average acceleration is the average over a time interval.
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]
kilometers.
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
For every second of acceleration the velocity is increased by that acceleration.

the general form of the units for acceleration are distance per time squared, such as m/s2.
You can't derive the velocity from the acceleration. Zero acceleration simply means that the velocity (at that instant) is not changing.
(any unit of length or distance) divided by (any unit of time)2 is a unit of acceleration.

units of acceleration
Assuming that your units of velocity are in units/second Acceleration = (velocity 2 - velocity 1) / time Acceleration = (4.9 - 0) / 3 Acceleration =1.63 *With correct significant figures the answer is 2
