If one worker produces 15 cones of ice cream in an hour, two workers produce 25 ice cream cones, and three workers produce 30 ice cream cones in an hour, what is the marginal return of production of the second worker?

The marginal return of production of the second worker or marginal product of the second worker is 10 cones.

Explanation:

One worker can make 15 cones of ice cream in an hour.

Two workers can make 25 cones in the same time.

While three workers can make 30 cones in an hour.

The marginal return of the production of the second worker is the contribution of the second worker in the total output.

Marginal return

= 25 cones - 15 cones

= 10 cones
