Answer: Approximately 4 hours and 27 minutes.

Explanation: Let Officer Kay's hours be represented by 1/8

and Officer Ming's hours be represented by 1/10.

That means that Officer Kay completes 1/8 of the job in 1 hour and Officer Ming completes 1/10 of the job in 1 hour.

If they work together,

It would be 1/8 + 1/10 =

Finding the LCM of the denominator, which is 80,

Addition of 1/8 and 1/10 is 9/40.

Let T be the amount of time it takes the two of them to finish the job,

then 9/40 of the job x T (expressed in hours) has to equal 1 job.

So, (9/40) x T = 1,

therefore T = 40/9 = 4.444 or 4 and 4/9.

Converting 4.444 to hours and minutes, we have 4 hours 27 minutes.

This means it would take 4 and 4/9 hours (about 4 hours and 27 minutes) for Officers Kay and Ming to complete the task together.

Hey there!

Erik Erikson developed and proposed 8 p<span>sychosocial stages of life. These, in order, are trust vs. mistrust, autonomy vs. shame, initiative vs. guilt, industry vs. inferiority, ego identity vs. role confusion, intimacy vs. isolation, generativity vs. stagnation, and ego integrity vs. despair. 

It sounds like the last one, ego integrity vs. despair, is described in your problem. The last stage begins around maturity, or 65, and goes on until death. At this stage, people are often retiring or are retired, and start pondering the things they didn't do with their lives. This leads to regret about not doing certain things that they once hoped to do, or maybe didn't even realize they wanted to do at the time. They think that it's too late now, and start feeling dissatisfied with their life, as your question describes. 

Hope this helped you out! :-)</span>
