Yvonne drove 11/2 hours to get to the airport. She arrived at 12.10A.M What time did she leave for the airport? Should she have lunch at the airport? why?

One hour earlier would be 11:10 AM. 1 1/2 hours earlier would be 10:40 AM.
It might be a good idea lunch to eat at the airport if she is flying, since domestic airlines no longer serve meals.
