Mean, median, mode

I came across a problem which began with;

"Mark ran a mean distance of 13.2km in 5 days"

Is this badly worded?

Yes! I'm assuming it means he ran  a total of T km in 5 days and his mean daily distance was 13.2 km. Work out T.

Without the word 'daily' it could mean all sorts of things.  Maybe that's his hourly rate!  (OK that's unlikely for a runner but math questions need to be worded clearly.)

Maybe the terrain was very rough and the temperature very hot and so the questioner thought it was mean for the organisers to set such a challenge.

Thanks, Bob, I was hoping it wasn't just me!
