How many minutes before 12 noon is it if 72 minutes ago it was twice as many minutes past 9am?
It is 36 minutes before noon, or 11:24 am.This is how I got it...Change all hours into minutes by first multiplying them by 60. For example, 1 o'clock would be (1) (60) or just 60.Noon or 12 = 720 and 9am = 540Now for X.X will be current time in minutes before noon and that equals noon-x or 720-x.Now, 72 minutes ago was current time... minus 72That make the equation 720-x-72Those minutes have to be twice as many past nine so you can write 540+2xNow, those two equations have to balance so 720-x-72=540+2xafter you subtract 540 from both sides and add x to both sides, you are left with 108= 3xdivide both sides by 3 and BOOM...3636 minutes before noon is 11:24Now to check...11:24 is 2hrs or (120 minutes) + 24 minutes past 9144 minutes11:24 minus 72 minutes (1hr + 10 minutes) is 10:12from 9 until 10:12 is72 minutes(2) (72)= 144.... It checks out.
How many hours and minutes occurred between sunrise and noon on May 30 2012?

How many minutes before 12 noon is it if one hour ago it was three times as many minutes after 8 am?
Between 8 am and Noon are 4 hours = 240 minutes. Let T = 240 - x, and T - 60 = 3*x. Where T is right now, T-60 is one hour ago, and x is the number of minutes before noon, and 3*x is the number of minutes after 8am. Substitute the first equation into the second & solve for x: 240 - x - 60 = 3*x --> 180 = 4*x --> x = 45, So it is 45 minutes before noon (11:15), and 1 hour ago (10:15) it was 2 hrs 15 minutes after 8 am (135 minutes), and yes 135 is 3 times 45, so it works.
What is 10 minutes to 3?
10 minutes to 3 refers to the time 2:50. This is because there are 60 minutes in an hour, and if you subtract 10 minutes from 3:00, you get 2:50. This can also be represented as 3:00 - 10 minutes = 2:50.
How many minutes is it before 12 noon if 28 minutes ago it was three times as many minutes past 10am?
If the time we're looking for is x, from 10:00 to 12:00 we have 3x + 28 min + x. The total time from 10 to 12 is 120 minutes, so 3x + 28 min + x = 120 min Subtract 28 min from both sides and add 3x + x... 4x = 92 min Divide both sides by 4... x = 23 min It's 23 minutes to 12.
