Answer:3
Step-by-step explanation:
The average acceleration of an object is calculated as the final speed minus the initial speed divided by the elapsed time.
So:

Where
= final speed
= initial speed
= elapsed time.
Thus:
The acceleration of the cyclist is:

a = 2.667
The acceleration of the car is:

a = 3.75 
The average acceleration of the car is higher than the average acceleration of the cyclist.
