Subtrahiere die $4h12\min 4h\backslash ;12\backslash min$ von $24h24h$.

$24\text{h}-4\text{h}12\min =19\text{h}48\min 24\backslash text\{h\}-4\backslash text\{h\}12\backslash min=19\backslash text\{h\}48\backslash min$

Addiere nun die errechnete Zeit zu den $3h17\min 3h\backslash ;17\backslash min$, um die Zeitspanne zwischen den beiden Uhrzeiten zu errechnen.

$19\text{h}48\min +3\text{h}17\min =23\text{h}5\min 19\backslash text\{h\}\backslash ;48\backslash min+3\backslash text\{h\}\backslash ;17\backslash min\; =\; 23\backslash text\{h\}\backslash ;5\backslash min$
