Your first example is a little extreme. There are questions about climb rate and ground speed, but usually the numbers are easily divisible in your head. For example, they might ask:
A plane is climbing 200 fpm and traveling at 120 mph groundspeed. What will the plane's altitude be after it has traveled 10 miles?
To me this question is MUCH easier to do in your head if you break it into 3 small, easier steps:
1) At 120 mph, the plane is traveling 2 miles per minute.
2) It will take the plane 5 minutes to travel 10 miles
3) 5 minutes x 200fpm = 1000 feet altitude
Your second question is easier if you break it down like this:
1) Plane A is traveling 2 miles per minute, Plane B is traveling 3 miles per minute
2) Since they are traveling in opposite directions simply add the rates... 2 miles per minute + 3 miles per minute equals 5 miles per minute divergence.
3)multiply 5 miles per minute divergence by 9 minutes and you get 45 miles.
I know it is easier when you have tons of time to think about it, but if you break it down into smaller pieces the problems get much easier to do in your head.
Hopefully that is helpful, maybe it provides you a different way of looking at these problems. But I don't think you will see anything like your first example, all of the problems I remember were much more easily divisible in your head. Don't stress too much.
