How many minutes is it before 12 noon, if 24 minutes ago it was 5 times as many minutes past 8 AM?
Answer:Let "x" be the number of minutes in the span of time between "now" and 12:00 noon. Then the span of time between 8:00 AM and "24 minutes ago" is 5x minutes. This diagram illustrates this: Point B represents "now", and point "A" represents "24 minutes ago". Together the three spans of time add up to 240 minutes, so the equation for this problem is
Solve for x to get x=36 minutes.
