<p>Convert all time units to the smallest unit before subtracting, then convert back to the original units. For example, Subtract 1:15:45 from 3:05:20</p>
13
<p>Solution: Convert everything to seconds. 3:05:20 is 11,120 seconds. 1:15:45 is 4,545 seconds.</p>

<p>Solution: Convert everything to seconds. 3:05:20 is 11,120 seconds. 1:15:45 is 4,545 seconds.</p>
14
<p>Subtract: 11,120 - 4,545 = 6,575 seconds.</p>
14
<p>Subtract: 11,120 - 4,545 = 6,575 seconds.</p>
