If it takes 45 minutes to make 15 chairs how long would it take to make 100 chairs.

45min/15 chair = 3min/chair

so, how long to make 100?

3 hours

no, 3 min/chair * 100 chairs = 300 minutes

That's 5 hours, not 3 hours.

To find out how long it would take to make 100 chairs, you can use the concept of proportionality. In this case, we can assume that the time it takes to make chairs is directly proportional to the number of chairs being made.

First, calculate the time it takes to make 1 chair by dividing 45 minutes by 15 chairs:
Time per chair = 45 minutes / 15 chairs = 3 minutes per chair

Next, multiply the time per chair by the desired number of chairs (100) to find the total time it would take to make 100 chairs:
Total time for 100 chairs = 3 minutes per chair * 100 chairs = 300 minutes

Therefore, it would take 300 minutes to make 100 chairs.
