Answer 2

Given,

The time 30 minutes before 10:15 pm is.

Solution,

Know that there are twenty-four hours in a day and sixty minutes in an hour.

Therefore,

$\[\begin{array}{l} \Rightarrow \left( {10:15{\rm{PM}}} \right) - \left( {30{\rm{Minutes}}} \right)\\ \Rightarrow 9:45{\rm{PM}}\end{array}\]$

Hence, the time $\[30\]$ minutes before $\[10:45\]$ pm is​$\[9:45{\rm{PM}}\]$.
