On the whole I think its quite a nasty question.
right 4 cars
now they could mean 5x4 + 3x0.02, ie 4 cars with 2 cm between them..
but it does say 'in each car space' which to me means one of those white rectangles .. so each space would be 5m + 0.04m (2cm each side

so the total would be 5.04 x 4 or 20.16m

hmmm.....

I seem to remember this question. Hasn't it got the word aproximately - or soemthing like that in it? I think we got the answer wrong because we were too exact!

would you really loose the mark for being sxact rather than approximate? It does seem rather pedantic to me!!!

Hi Guest

It depends on whether the question is multiple-choice or not. There are quite a few estimate, approximate, roughly type questions that come up, but the actual correct answer does not occur in the answer options.

I remember this question: it DOES depend on whether it is multiple choice. The latter provides a rough (approximate) answer which you have to choose. Because I did not provide my kid with the multiple choice answer booklet on the day that he did this question, he gave me the exact answer along the lines developed above.

It is a very poor question - how could cars park in such a space!! Totally unreliastic - the sort of 'everyday' probelm that just hasn't been thought through!!

I think the added space per car was about 1.5m. The answer from memory is 27.5m, but the approximate answer is 28m. The trick to this is to read the question.
