Ages ago,I came across this 11+ question,yet did not write down the answer and cannot remember where I got it from. A friend and I are baffled about what it is needed and how to do it. Can anyone help,please? Is something missing in the question or there is a reason for this?

Accuracy categories 1.casual measurements, 2SF
2. important or technical things (3SF)
3.really scientific work (3 or more SF)

a) estimate distance of a journey 320miles, 15 miles or 2 400 miles

b) estimate area of a garden/floor 480m square or 18m square

It strikes me that there is definitely something missing, although (b) makes some sense in that '18m square' could be a garden or a very large room.(18 square metres' would be post of room-size or a rather small garden).

'Distance of a journey' could be any of those given...

Thanks,but what accuracy category it belongs to,or any of these figures when they are all whole numbers?I think that is what they asked,to put the answer into a category.
