Question

Two workers working 9 hours made 243 parts. Worker A makes 13 parts in 1 hour. If the workers work at a steady rate throughout the day, who is more productive, Worker A or Worker B?

Answer 1

To determine who is more productive, let's calculate the production rate for both Worker A and Worker B.

Worker A:
Production rate = 13 parts per hour

Worker B:
Since two workers together made 243 parts in 9 hours:
Production rate for Worker B = Total parts made by both workers / Total hours worked by both workers
Production rate for Worker B = 243 parts / 9 hours
Production rate for Worker B = 27 parts per hour

Comparing the production rates:
Worker A: 13 parts per hour
Worker B: 27 parts per hour

Worker B is more productive as they can produce 27 parts per hour, while Worker A produces 13 parts per hour.
