It can't be done. You can see the available controls by looking at the Control menu at the top, 4th from the left. There is nothing about playback speed. Sorry.

You can't do it in iTunes, but....
You can drag the audiobook from the iTunes books library to the Mac's desktop. Then you can use Quicktime 7 to play from 1/2 to 3X speed. Use the QT Window menu > Show A/V controls and use the playback speed slider at the bottom right of the A/V window. If you don't have QT7 player in your Applications/Utilities folder, this explains how to get it: http://support.apple.com/kb/HT3678
