Answer:
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
