Answer 2

Problem Analysis

We are given that a worker produces an equal number of parts every hour and that in 4 hours, the worker produced "b" parts. We need to determine how many hours it will take for the worker to produce 90 parts using the same rate.

Solution

Let's assume that the worker produces "x" parts per hour. According to the given information, the worker produces "b" parts in 4 hours. Therefore, we can set up the equation:

4x = b

To find the number of hours it will take for the worker to produce 90 parts, we can set up another equation:

hx = 90

where "h" represents the number of hours.

To solve for "h", we can rearrange the equation:

h = 90 / x

Now, we need to find the value of "x" to substitute into the equation.

Calculation

Since we don't have the value of "b" or "x" directly, we need to find a way to determine them from the given information. Unfortunately, the search results provided by You.com do not contain the necessary information to solve this problem. Therefore, we cannot provide a specific answer based on the given information.

However, if you have any additional information or if you can provide the value of "b" or any other relevant details, I would be happy to help you solve the problem.
