So, Copper went into the store at 4:40 p.m. then came out at 5:13 p.m.
One way to visualize this is to first count the minutes to 5:00 p.m. and then add the minutes after that. So, there is 20 minutes till 5:00 p.m., and then 13 minutes until 5:13 p.m. 20 + 13 = 33 minutes. This makes it easier to see how long Copper took in the store.
Hope this helps!! If you have any questions about my work, please let me know in the comments!
