Problem
It is 3.30pm and you are working on a task that the manager of the centre has asked you to complete. The task you are working on should only take you another 30 minutes. Julie approaches you and asks you to complete some paperwork. The paperwork needs to be done by 5pm but should only take 20 minutes to complete. Julie asks you what time you will be finished your current task and if you will be able to have the paperwork done by 5pm.
