If a person is 83 and a half years old (11hrs 58 min) and there life span is a 12 hour clock how old will they be at 12 hours or in two minutes..

Please clarify the question - what do you mean by "83 and a half years old (11hrs 58 min)?" And what do you mean by "there life span is a 12 hour clock?" I'm guessing that what you mean is the person was born 83 and a half years plus 11 hours, 58 minutes ago? And that the person uses a 12-hour clock - is that right?

I believe it is a ratio type problem. What they mean is that the person's entire life can be represented by 12 hours. They are near the end of their life at 11 hours and 58 minutes, which is analogous to 83 1/2 years.

If 83 1/2 years is 11 hrs and 58 minutes, how many years is 12 hours?

\frac{83.5}{11.96666}=\frac{x}{12}

x=83.7326

More accurately, x=\frac{30060}{359} years old at 12 o'clock.

I reckon I done that correctly. :confused:

Agreed!
