Volunteers at the refreshment table. Both workstations allow volunteers a short break, but at different intervals. The prize table allows volunteers a short break every 20 minutes, but the
refreshment table allows a short break only every 30 minutes. If the party is scheduled to start
at 2:00 pm and Brad and Stella both start working then, what is the first time that they will be
on break together? Show all work.
Please help i have to turn the work in a couple of hours!
