Question 1136827

If a digital clock reads 4:56, how many minutes will pass before all the digits are in a consecutive and increasing order again?
<pre>The next time would be: 5:67 - which is 6:07, but a digital clock will not display this. It can't be 0:12 because a digital clock doesn't display that either.
Therefore, it MUST be 1:23, and when 4:56 is subtracted from 1:23 (13:23 in military time), we get:  13:23  -  4:56 = 8:27, or 8(60) + 27, or {{{highlight_green(matrix(1,2, 507, minutes))}}}
