ten minute' walk or ten minutes' walk?

elaborating on the answer above...a 'ten-minute walk' is a noun.
otherwise it is 'ten minute's walk'

eg Q: how far is it to walk to the bar?
A: it's ten minutes' walk from here (or if u want to use the noun: it's a ten-minute walk from here)

as for why - the A is saying 'it's a walk of ten minutes from here' so it is used like 'the possession of Ben', which is the same as 'Ben's possession' and not abbreviated form (like it is = it's)

Also the apostrophe is after the 's' because it is plural. if it is singular then it is before the 's', eg. minute's walk

sorry typo on the 1st 'ten minutes' walk'

Both are wrong.

The correct one is "ten-minute walk".

Similar example is "a seven-year-old boy".
