Answer:
y = -3/2x + 3
Step-by-step explanation:
y = -3/2x + 3
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.
I would say the answer is E. The coach cannot select those he observes. the reason being is because all people can run a different time due to the age of the person, not saying that they have a limit but the question leaves out how fit the player is. to put in words a athletic person on the average could run about 4-5 laps depending on how far each lap is. Hope that helps
Divide both sides by negative two
the answer is x = -1
