Answer:
A. 8.
Step-by-step explanation:
The marginal product is the increase in output (units produced) resulting from employing one more worker. Therefore, the marginal product of the second worker (M2) is given by the difference between the total product with two workers and the total product with one worker.

The answer is A. 8.
16 added to the product of 1/2 times 8, and then subtracted by 6.
16+4-6=20-6=14
Speed=Distance/Time
So Distance=Speed X Time
Distance=55T
Where 55 is the Car's speed and it is constant(won't change) and T is the time which is the changing variable.
you can plug time values to know the distance traveled!
6.26 because 20 subtract 13.74= 6.26
