How many hours does your AC run per day?

Over the past week or so with these warmer temps my unit has run for 8-11 hours on average per 24 hour period. Not sure how normal or unusual that is. It’s a 1850 sq ft single family house (50 years old) with a 3.5 ton unit. New ductwork and impact windows/doors throughout. We also keep it warm at 78 degrees inside and have attic insulation.
