1. Hi all,

I’ve got a job interview on the 30th of November and I’m expected to do a aptitude test, I’m sure most of you have come across them before. I’ve been working fairly hard on getting my maths up to scratch (Taken two week’s holiday off work to prep for it). Anyway, I’m expecting part of this aptitude test to have questions like the following:

“You are burning 4Kgs of fuel per minute. How much fuel will you need for a 220mile trip if you average 150mph?”

Now I do get the answer to these questions, but there must be a problem with my technique, I take ages doing them almost 50 sec’s which is game over for what I’m going in for. Can anyone post a technique which can increase my speed in doing these types of questions?

Any help would be greatly appreciated.

2. time = distance/speed

= 220/150
= 1.47 hours = 88.2 minutes
88.2 x 4kg = 352.8 kg of fuel

Do you know the speed/distance/time formula? If you do I don't see why it should take you so long?
