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.

The writer stayed through one week volunteering at an eye healing facility in India where a huge number of patients recover their sight every year. He was profoundly touched by the dedication of Dr. V and his team to helping their patients. The experience appears to have impacted the writer's own particular point of view.
