On Planet Plex, there are only six hours in a day but the days of the week are the same as ours. Arog the alien lives on Planet Plex.
Here is a clock which shows how Arog spends each hour of the day during the week:
What time does school start?
Arog starts his dinner at $4$ o'clock. What will he be about to do two hours later? What was he about to do five hours earlier?
Arog gets into bed on Wednesday evening. How long is it until school finishes on Friday?
