Answer 3

Problem Analysis

To solve this problem, we need to calculate the number of parts an experienced worker will produce in 7 hours, given that they produce 4 more parts per hour than the apprentice who produces 18 parts in 6 hours.

Calculations

The number of parts produced by the apprentice in 1 hour is 18 / 6 = 3 parts per hour.

The experienced worker produces 3 + 4 = 7 parts per hour.

Therefore, the experienced worker will produce 7 * 7 = 49 parts in 7 hours.

So, the experienced worker will produce 49 parts in 7 hours.

Conclusion

The experienced worker will produce 49 parts in 7 hours.
