Show Hint
Translate each statement into a timeline. Time problems become very easy once all events are placed chronologically.
Step 1: Determine Q's arrival time.
P arrived at
\[
10:10\text{ am}
\]
P was 20 minutes later than Q.
Hence Q arrived at
\[
10:10-20=9:50\text{ am}
\]
Step 2: Use the condition regarding the schedule.
Q came 30 minutes before the interview.
Therefore,
\[
\text{Interview time}
=
9:50+30
\]
\[
=10:20\text{ am}
\]
Thus,
\[
\boxed{10:20\text{ am}}
\]
