Math Problem VI

You are attending a college undergraduate commencement ceremony. One of the commencement speakers has told you that there are 1,400 students graduating on this day, and they are all to line up as someone reads their name and someone else shakes their hand. You count twenty names read during the first minute. If the first name was read off at 10:06 AM, what time will it be when the last name is read?

If 20 students can be read off in a minute, then each name takes about three seconds (60 sec / 20 names = 3 sec / name).

(3 sec / name)(1400 names)(1 minute / 60 seconds) = 70 minutes.

The final name will be read at 11:16 AM.
