If a car accelerates from 10 m/s to 30 m/s in 5 seconds, what is its acceleration?

Acceleration = (30 - 10) / 5 = 4 m/s²

How does the concept of the “conventional value” of physical constants, such as the speed of light, play a role in the SI system?

The speed of light in a vacuum is fixed at 299,792,458 m/s\ in the SI system. This value is used in definitions of other units, such as the meter.
