Divide miles, speed time formatting

Hi, I am trying to display in minutes, instead of 0.2 hr etc
like the example below will do, now I know every .1 = 6 min
I am just stumped on how to get this to display 12 minutes.

PHP Code:
$sum = round(11 / 55,1);// example 11 miles
echo $sum;
I am trying to display things in minutes only when under 1 hour
Anyone know how to multiply just that number after the decimal by 6?

 

Multiply it by 60.

<?php
$sum = round(11 / 55,1);// example 11 miles
$cal = $sum * 60;
echo $cal." minutes";
?>

PHP:

 

He only wanted to multiple the decimals not the whole number.

<?php
$sum = round(11 / 55,1);// example 11 miles

$hours = floor($sum);
$minutes = ($sum-hours) * 60;

echo $hours. " hours and " .$minutes. " minutes";
?>

PHP:

 

I must've misread when he wanted it to display "12 minutes"

 

I can't tell whether that's sarcasm or not. If it is:

 

Don't have any idea about PHP. If anybody knows, please help.

 

No not sarcasm, I misread.

Your code does output an error though, but the fixed code:

<?php
$sum = round(11 / 55,1);// example 11 miles

$hours = floor($sum);
$minutes = ($sum-$hours) * 60;

echo $hours. " hours and " .$minutes. " minutes";
?>

PHP:

 

Sorry about that.

oops I was testing my code with a fresh installation of xampp and it had error_display disabled.
