Hi there!
First, we know that the remaining time until 6 PM is 7 minutes. So, we can subtract 7 minutes from 47 and now we have 40 minutes left to add and it is 6 PM. Next, since 40 is not more than 60 minutes, we'll add 40 minutes to 6 PM. This leaves us with the time 6:40.
ANSWER:
He arrived at 6:40
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
