Question

how many minutes is it before noon, if 70 minutes ago it was four times as many minutes past 9 am?

Answer 1

$<b>$12 noon = 12 x 60 = 720 minutes


9 am = 9 x 60 = 540 minutes


Let x = number of minutes before noon


The time now is 12 noon -x = 720 -x minutes


48 minutes ago it was 720-x-48


720 -x - 48 = 540 + 2x


720-48-540 = 3x


x = 44 minutes 


It is 44 minutes before noon, or 11:16 am



Thanks


Have a colossal day ahead
