Explanation:
The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.
The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:
speed = distance / time
Therefore,
distance = time × speed
distance = 15 × 65
distance = 975 miles
Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:
speed = distance / time
time = distance / speed
time = 975 / 50
time = 19.5 hours

Assuming no other variable costs, the marginal cost of a taco is; $5
Formula for marginal cost is;
Marginal cost = change in cost/change in quantity
We are told the cost of hiring an additional worker is $200.
Thus; change in production cost = $200
We are told that the marginal productivity is 40 tacos. This marginal productivity of the change is cost is the change in quantity.
Thus;
Change in quantity = 40
Finally,
marginal cost = $200/40
Marginal cost = $5
