Math

Susan and Matthew's mom went on a business trip. Their dad is the only one in the family who can drive now. On Sunday, Susan has dance class from 11:00 am to 1:00 pm. Matthew has basketball from 1:30 pm to 2:30 pm. It takes 15 minutes to get to dance class from home and 20 minutes to get to basketball from home (both by car). It takes 20 minutes to get from dance to basketball. In addition, Susan has a fencing competition from 2:30 pm to 6:00 pm. It take 30 minutes to get to the competition site. Lastly, all of them, including Charles, have to eat lunch at some point. How will Charles be able to bring them to their events on time?
