Answer:
He wakes up at 6:20 am!
Explanation:
First we find how many minutes Tim walks to school.
60/12 = 5 Basically we are finding how much 1/12 is and multiplying it by 5, we can use other ways to, but this is how I do it.
5x5=25
7:35 - 0:25 = 7:05 am is the time for Getting Ready For School
3/4 = 60/4 = 45 min
7:05 - 0:45 = 6:20 am is the time Tim woke up.
