I know that the matter of STD is something that has been discussed regularly and probably to death, however I wanted to ask people's opinions on doing a couple of questions as my maths is pretty weak and I am sure there is probably a faster way of doing them! As you can probably guess I am preparing for my FATS, anyway these are questions I got from the link below which I found on an earlier thread on here

just if anyone is interested.

So the first question is;

You burn 30kgs of fuel per minute. How much do you use in 45 minutes?

Now to do this I would just multiply the 30kgs by 45 - is it really that simple? (there are no answers on the site so I cant be 100% certain and as I said my maths is pretty bad).

The next two are a little more complex;

You have used 280kgs of fuel in the past 80 minutes. How much do you burn per hour?

You travel 330 miles. How much have you used if you burn 160kgs an hour, if you are travelling at 220mph?

How, in the interest of doing them as quickly as possible, would you say was the best way to do these sums as I am a bit bamboozled by them since they aren't your standard, your speed is 360mph and you go for 20 mins, what distance do you cover type question?

Thanks to anybody that contributes to this, I am really interested to see everyones different methods, in a hope that I might be able to use one myself!

Cheers
