Problem Statement

You are asking how many sheets the second machinist will print in the same time if she prints 3 sheets less per hour than the first machinist, who prints 72 sheets in 8 hours.

Solution

To find the number of sheets the second machinist will print in the same time, we need to determine how many sheets she prints per hour and then multiply that by the number of hours.

Let's break down the problem step by step:

1. Find the number of sheets the first machinist prints per hour. - The first machinist prints 72 sheets in 8 hours. - To find the number of sheets per hour, we divide the total number of sheets by the number of hours: 72 sheets / 8 hours = 9 sheets per hour.

2. Find the number of sheets the second machinist prints per hour. - The second machinist prints 3 sheets less per hour than the first machinist. - Subtracting 3 sheets from the first machinist's rate, we get: 9 sheets per hour - 3 sheets per hour = 6 sheets per hour.

3. Calculate the number of sheets the second machinist will print in the same time. - The second machinist will print for the same 8 hours as the first machinist. - To find the total number of sheets, we multiply the number of sheets per hour by the number of hours: 6 sheets per hour * 8 hours = 48 sheets.

Therefore, the second machinist will print 48 sheets in the same time.

Answer

The second machinist will print 48 sheets in the same time as the first machinist, given that she prints 3 sheets less per hour than the first machinist who prints 72 sheets in 8 hours.
