To determine how many more weeks it would take for Sam to complete the minimum required hours to become a dental assistant, we need to first know the total hours required for certification.
Assuming the minimum required hours to become a dental assistant is 300 hours, we can calculate the remaining hours Sam needs to complete:
- Sam has already completed 150 hours.
- The minimum requirement is 300 hours.
- Remaining hours = 300 - 150 = 150 hours.
Next, we calculate the rate at which Sam is working. In the past four weeks, he completed 150 hours, which means:
150 hours / 4 weeks = 37.5 hours per week.
Now, we can determine how many weeks it will take Sam to complete the remaining 150 hours at his current rate of 37.5 hours per week:
Remaining hours / weekly hours = 150 hours / 37.5 hours per week = 4 weeks.
So, it would take Sam 4 more weeks to complete the minimum required hours to become a dental assistant if he continues at the same rate.
The answer to your question is four weeks.
