I'm calculating the amount of time that an electric plant can operate with a
certain amount of gas, let's say:
A plant can work an hour with 10 galons, How long does it will work with 300
galons?
hrs = (300 galons / 10 galons) = 30 (I could also have a float here!!!)
Then, I have the time the plant was refilled, let's say 16:42, so I need to
calculate the next hour the plant needs to be refilled. Like 16:42 hrs + 30
hrs
How can I sum these two values?
How can I convert the integer or float value 30 to a hour format?
With absolutely no testing and horrible variable names....
$x = "16:42";
$y = 30;
list($h, $m) = explode(":", $x);
$x1 = $h + $m/60;
$total = $x1 + $y;
$h = floor($total);
$m = floor(($total - $h) * 60);
$newtime = "$h:$m";
