Answer 3

Problem Analysis

We are given that a master can produce 24 parts in 3 hours. We need to determine how long it will take for the master to produce 45 parts if they increase their production rate by 1 part per hour.

Solution

Let's break down the problem step by step:

1. We know that the master can produce 24 parts in 3 hours. This means that their production rate is 24 parts / 3 hours = 8 parts per hour.

2. We are also given that the master will increase their production rate by 1 part per hour. Therefore, their new production rate will be 8 parts per hour + 1 part per hour = 9 parts per hour.

3. To find out how long it will take for the master to produce 45 parts at a rate of 9 parts per hour, we can use the formula:

Time = Number of parts / Production rate

Plugging in the values, we get:

Time = 45 parts / 9 parts per hour = 5 hours.

Answer

Therefore, it will take the master 5 hours to produce 45 parts if they increase their production rate by 1 part per hour.
