Mathematical Question

[rsvp]

I have a measuring wheel marked in meters - I want to measure different length courses and be able to find the time required to compete each course whilst moving at a rate of 220 yards per minute. I have worked it out but in a very long and complicated way - I'm sure there must be a much easier method than the one I'm using. Any help gratefully received. Many thanks

I'm not sure I quite understand the question, but it would be easier if you work in the same units throughout. So change 220 yards per minute to 3.353 metres per second.

Agree with jo ...............

Time = course length divided by 3.353

[rsvp]

appreciate that cloverjo - that's my problem! think what I have to do is to convert the metric length of the course to yards first. Once I have that length I can divide it by 3.66 (220 yards per minute = 3.66yards per second.)

[rsvp]

Now why do I get 3.66 and you guys get 3.35?

[sunny-dave]

Because they are including the change from metres to yards, which you have done separately ... I think ...

[Cloverjo]

Yes. Sunny dave is right. Mine is metres per second. Yours is still in yards per second.

[rsvp]

thank you Sunny Dave _ think I need to go and lie down in a darken room for being so thick!

If your measuring wheel is in metres it seems far simpler to me to do everything in metres in the way Cloverjo, The Builder etc have suggested. You then never need to do any conversions

[rsvp]

thank you factor fiction and I fully agree with you - however, the speed has been given to me in yards per minute whereas my measuring wheel is in meters - hence my question.
