Santa Claus sometimes helps the elves by making some toys. He’s not as fast as the elves, but he can still make 30 toys each hour. In order to keep from getting bored he starts each day by building 50 trains and then switches to building 50 airplanes. Then he switches back to trains and keeps switching back and forth until the day is finished. If Santa starts work at 8:00am, when will he finish his 108th train?
