Yup - you're right - some people can work this out in their head. For those who can't or want confirmation of their calc this is a decent way of doing it. Of course a calculator will do it to - what ever - we're just presenting a solution and helping those who want to be helped. Thanks for your comment. Of course if the head gets it wrong and it causes a crash - the officers might say more than discuss being dumb. Good discussion topic!
