Abstract

[Introduction] How many person-hoursare spent listening to graduation speeches each year? How long is this in lifetimes?

Answer: Just about everyone graduates high school and goes to their graduation, usually with guests. Only about 30% of Americans (more than 10% and less than 100% graduate college, so we will ignore those graduates. Therefore we need to estimate the number of graduating high school seniors, the number of guests per senior, and the length of the graduation speeches.
