Answer: Tina spends 35 minutes reading.
Explanation:
If Tina wakes up at 7:00 am and spends 10 minutes eating breakfast and 15 minutes getting ready for school that puts her at 7:25 am. If she leaves for school at 8:00 am then that means she had 35 minutes to read before heading on her way.
7:00 + 10 = 7:10
7:10 + 15 = 7:25
There are 60 minutes in an hour therefore, 60 - 25 = 35.
