Answer 1

12:30 P.M.

Explanation:

Emily took 30 minutes to make the dough and 1 hour to bake all of the cookies. In total, that's 30 minutes + 1 hour = 90 minutes (1 hour and 30 minutes). If it were 1:30 P.M. when Emily took the last batch of cookies out of the oven, then 90 minutes before that would be 1:30 P.M. - 90 minutes = 12:30 P.M. So, Emily started making the cookies at 12:30 P.M.
