Question

A worker on a assembly line is required to take a short break every 120 to 150 minutes.The worker begins his job at 9:45 AM.Which is not a time the worker could take his first break

Answer 1

Answer: The worker can not take his first break before 11:45 AM

Explanation:

120 minutes = 2 hours

150 minutes = 2 hours 30 minutes

if the worker begins his job at 9:45 am and he is required to take a short break every 120 to 150 minutes from the time he resumes, then he can take his break 2 hours to 2 hours 30 minutes after 9:45 am.

So, 9:45 am + 2 hours = 11:45 am,

or 9:45 am + 2 hours 30 minutes = 12:15 minutes, the worker can only take a short break from 11:45 am to 12: 15 pm

Therefore, the worker can not take his first break before 11:45 AM
