Halil arrives home from school at 6.09 pm. He is very hungry! A note says that the meal in the oven needs 2 hours and 20 minutes to cook, and it went into the oven at 4.15 pm. How long does Halil have to wait until the casserole is done?

Answer 1

Halil needs to wait 26 min.

Answer 2

4:15 to 5:15 1 hour
5:15 to 6:15 2 hours
6:15 to 6:25 2 hours 10 minutes
6:25 to 6:35 2 hours 20 minutes
The casserole is done at 6:35. Since it is 6:09 when Halil arrives home,
6:09 to 6:35 is 26 minutes.
