Answer:
D) 2:20
Explanation:
From 4:15 to 5:00 gives 45 minutes
Fro 5:00 to 6:00 gives 60 minutes
from 6:00 to 6:35 gives 35 minutes
Now lets add all minutes together
45 + 60 + 35 = 140 minutes
Convert to hour and minutes
Remember that 60 minute make an hour
So we can get 2 60 minutes (2 hours) from 140 minutes and 20 minutes left
Hence, she spent 2 hours 20 minutes or 2:20
