The ten- minute...

A ten-minute-old baby is one that was born ten minutes ago. I suppose a ten-minute-old minibus could be one that rolled off the assembly line ten minutes ago. It has nothing to do with the timing of its route. These phrases you are trying to use as adjectives don't convey what you want them to convey.

No,
I don't mean its age is ten - minute or something like that.I mean the old bus that comes every 10 minutes.

If you want to describe the minibus as being old you could say "The old ten-minute minibus..."

Even ignoring the problem of where to put "old," "the ten-minute minibus" doesn't make any sense -- at least in English. Maybe in your language you can say "the ten-minute bus" for a bus that comes every ten minutes and everyone knows what you're talking about, but it just doesn'twwork in English. Saying "the every-ten-minute bus," is a little better, but it's still not very natural. Ju

Anonymous1- The ten- minute old minibus is over there. I mean by" ten - minute" the bus that comes every 10 minutes.Is it correct?

No. The only kinds of nouns that can take that kind of adjective are nouns that represent events that take a certain length of time to complete.

a ten-minute trip
a ten-minute ride
a ten-minute conversation

Thanks, CJ -- I couldn't explain why it sounded so wrong to me.

Is this sentence correct?
The every- ten- minute old minibus.
Where does " old " have to be placed after " every- ten- minute" or before.

It's not correct. The word "old" does not belong there.
