    <img src=/S/scratch.gif border=0 alt=scratch width=25 height=29> - My solution does not match yours. <span style="background-color: #FFFF00; color: #FFFF00; font-weight: bold">I got 37,039 feet.</span hide> I didn't say you were incorrect! I've attached my workbook. If you get a chance, maybe you can show me where I went wrong. <img src=/S/confused.gif border=0 alt=confused width=15 height=20>

    Re: Helicopters & Boats

    I redid it using my method (essentially the same as yours) and arrived at the same answer as you did. Initially, I was fiddling with two instances of Windows Calculator (since each instance only has one memory) and I doubtless hit a wrong button somewhere. Sometimes I feel like dragging out my old log tables... at least you know where you are then!
