Answer 2

Solution:

The worker was supposed to make 3 parts per hour to complete the task on time. However, he made 1 part per hour more and finished the work 4 hours ahead of schedule. To find out how many parts the worker was supposed to make, we can use the following formula:

Let's denote: - x = the number of hours the worker was supposed to work - y = the number of parts the worker was supposed to make

Given: - The worker made 1 part per hour more than required, so the worker made (3 + 1) = 4 parts per hour. - The worker finished the work 4 hours ahead of schedule.

Using the formula: 1. The total number of parts made by the worker can be represented as x * (3 + 1). 2. The total number of parts required to be made is 3x.

Equation: 3x = 4(x - 4)

Solving for x: 3x = 4x - 16 x = 16

Substituting x back into the equation to find y: 3 * 16 = 4 * (16 - 4) 48 = 4 * 12 48 = 48

So, the worker was supposed to make 48 parts.
