What is an average 5km run time for a 40 year old male?

Was wondering about timing for others to swim this distance -- I swim around 5K per day, probably 5 or so days per week on average -- approx. time is around 1 hr 30 mins or 1 hr 45 mins, nonstop swimming. Note that I've just gotten back into swimming this summer after a break of 2 yrs or so, but when younger I swam daily during summers.

Late 30s male in pretty decent shape, 6' + and a little over 200 lbs.
