Answer:
In an inertial frame of reference, Speed=Distance/time.
Given here, speed= 72km/hour= 72km/3600seconds=72000m/3600seconds
That is, speed=20m/s (International System of Units)
For time= 2 seconds, distance=speed*time (just rearranging the above formula)
Therefore Distance traveled by the car=20*2m=40
