Hi salamor,
I just passed my second attempt at the aircrew testing today so luckily for you my mind is still fresh on the content. I personally have a few practice tests from paid sources in hard copy form so unfortunately I can't give you those...but I have found some other good sources.
Firstly, the maths is fairly basic and anyone who meets the minimum requirements for applying for pilot should do just fine. That being said, you can find specific examples of very similar time/speed/distance questions here:
Speed/Distance/Time Qs
Secondly, there is not really any way to prepare for the hand/eye coordination tests, as they really do test your base skills in that area. However, do make sure you are good with your times tables as part of the test with the touch pen and joysticks involves them. If you have a smart phone or tablet, I suggest downloading an app from GooglePlay or the apple store called GetYourWings by Blue Horizon Enterprises. It has some good practice questions including the hand/eye coord tests.
Lastly, have a read of this from the New Zealand defence force:
NZ Aircrew Aptitude test
They use a very similar testing system.
I hope this helps a little
