Please help!

we can think of this as a timeline, where our point is x units away from 12:00, and 99 units the other direction, there is a point 2x units away from 8:00

this turns into an equation:3x+99=240 we will just solve for x:

3x=240-99=141

x=$\boxed{47}$minutes away from 12 P.M.

Note  that   there  are  240  minutes  between  8 AM  and 12 PM

Let  x  be  the  number  of  minutes  before 12PM

So

2x   +  99   =   240  -  x

3x  =  240  -  99

3x  = 141

x =  141 / 3  =  47  minutes   until  12 PM
