Andrew1991,
You are right but more of the latter where you don't get a simple s=d/t but need to work a little more. So expect a 3 - 6 sentence questions as opposed to straigth for s=d/t questions. Also check my posting to ianb87 on another type of question on page 227.
The time is exactly 15 minutes for 20questions for SDT
20 minutes for 40questions for cubes
20 minutes for 50 questions for diagramming
18 minutes for 30 questions on ATC motivation paper
