He came back half an hour later.
At what time did he come back?
Jack comes back at 10:00.
Half an hour is 30 minutes.
The time shown on the clock is 9:30, or half-past nine.
He went to the shops and came back half an hour later, which means he was out for 30 minutes.
Half an hour, or 30 minutes after 9:30 is 10:00.
