Answer
ahi jose
that sounds like enough exercise daily for your age.  U could also bike some if u have a bike, that is good for peoples heart.
but at least your walking some and that is great for your body and mind.  keep it up and try to increase it to one mile or two a day.  do not go by time go by mileage.

warm regards
patt n good luck
