Answer:
It will be ready at 6:15
Explanation:
So you've got 2:45 for it to cook and it's been placed at 3:30. You can put it simply like:
2:45+3:30=x
x would represent the unknown time, all you need to do is add.
It's 5:75, but an hour only goes to 60 minutes and you've gone to 75.
You have to subtract 60 from the minute marker and add an hour:
5:75
-60
6:15
