Hint: Convert $20hr$ $5min$ in such a way that it is easier to subtract the other entity with it.

Complete step-by-step answer:

$20hr + 5\min = 19hr + 1hr + 5\min $

We can write $1hr$ as $60mins$,

Therefore,on adding the minutes, we get,

$20hr + 5mins$ = $19hr + 65mins$

Now, we can perform the subtraction,

$19hr$ $65mins$ - $12hrs$ $58min$

$Answer$ = $7hrs$ $7mins$

Note: You can also convert the minutes to hours, but it will involve fraction, so it is better if we convert the hour to minutes.
