The machine make nails at a rate of 8th pounds per hour
<h3>How to determine the rate of making machine?</h3>
From the question, the given parameters are:
- Amount of pounds of nails = 4th pounds
- Number of time = half an hour
The rate in pounds per hour the machine make nails is then calculated as
Rate of making nails = Amount of pounds of nail/Number of time
Substitute the known values in the above equation

Rate of making nails = 4th pounds/0.5 hour
Evaluate
Rate of making nails = 8th pounds per hour
Hence, the rate of making nails is 8th pounds per hour
