How many minutes before 12 noon if 44 minutes ago it was 3 times as many minutes past 9am? Please solve it. Thanks!

First of all you convert the time into minutes like 9*60 = 540 minutes 12*60 = 720 minutes Suppose x is the number of minutes before noon then, T = 720-x. 44 minute ago is t-44 3 times past 9am is t-44 is equal to 540+ 3x t = 584 + 3x now you can solve it like t= 584+3x………..i t=720+3x……………2 taken first equation t=584+3x put the value of t in equation 720-x=584+3x 4x= 136 X=34

Change all hours into minutes past midnight, so 9am = 540 and noon = 720.
Let suppose x be the number of minutes before noon it is now, so present time t is = 720 - x.
44 minutes ago (t-44) it was 3x past 9am: t-44 = 540 + 3x.
No you have simultaneous equations to solve: t = 720 - x t = 584 + 3x
cancel out t's: 720 - x = 584 + 3x 136 = 4x x = 34
Now it is 34 minutes before 12 noon.
difference between 9 am and 12 noon= 180 min let x min ago was the time when 44 minutes ago it was three times as many minutes past 9 a.m. so 44 min ago when time was x min to 12 noon time was 3x min past 9am so total min in time interval 9 to 12 are 3x + 44 + x = 4x + 44 hence 4x + 44 = 180 or 4x=136 so x=34 min so time was 34 min before 12 noon, i.e., 11:26 when 44 min ago it was 3 times as min as many min past 9 am
I think it might be 44. I am not sure about it.
