Answer:
Sally leaves her house at 7:15 am, and reaches home again at 1:00 pm.
Step-by-step explanation:
She starts at a time(?) and gets to school at 8 am. It takes her 0.75 hours to get there. So, do 8 minus 0.75 hours and you get 7.25. So she started at 7.25, or 7:15 am since 0.25 is a quarter of an hour, or, 15 minutes.
So she left at 7:15 am, got to school at 8 am, and school took 5.25 hours. So start at 7:15 and add 5.25 hours, and you get 12.5. 12.5, or, 12:30 since 0.5 is half an hour, or, 30 minutes.
Then she had to go back home which took 0.75 hours, or, 3 quarters of an hour which is 45 minutes. So since school was done at 12:30, add the 30 minutes (her journey back home), and you end up at 1:00pm.
