This answer is incorrect.
The easiest way to do this problem is to start at 3:45 p.m., then add the 15 minute walk to the dancing class. This means that she would get there at 4:00 p.m., she stays one and one half hours, this means that she would leave at 5:30 p.m. Then you have to add the 15 minute walk home, which brings it to 5:45 p.m.
Now let us try another one
Harry leaves for school at 7:30 a.m. It is a 20 minute walk to school. He stays in school for 7 hours and 40 minutes. He then goes to basketball practice for 2 hours and then walks home. What time does Harry get home.
