If you have a cafe open from 7 am to 8 pm, isn't this 13 hours of operations? I would calculate it as 20 (8 pm conversion to 24h format) - 7 = 13, isn't this how you do it? I saw a prompt say it's 14 hours of operation.

Hi there,

Cases are not the gospel! Cases make mistakes. In fact, I see mistakes in about one our of every 2 or 3 cases. This is normal, but doesn't inherently mean the case is a bad one.

7am-8pm is indeed 13 hours

Hey there,

Agree with Ian here. No need to overcomplicate it. Yes, that are 13 hours :-)

Cheers,

Florian

Yep, 7am to 8pm is full 13 hours of operation.

Must be a typo.
