Step-by-step explanation:
Step-by-step explanation:
1 * (-5) = -5 a = -5
6 + (-5) = 1 b = 1
1 * (-5 ) = -5 c = -5
-7 + -5 = -12 d = -12
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.
