Vivian is going to do some yard work, but she needs to leave her house at
2:00 to go to a football game. She is going to mow the lawn for 1 hour and
15 minutes, trim some bushes for 40 minutes, and put down some mulch for
25 minutes. She will also need 30 minutes to shower and get dressed. What
time should she start the work so that she will be ready at 2:00?
