How fast does a professionally hit volleyball travel?

Question

I am watching the olympics, and have converted the serve speeds to 66 mph, but i would imagine they go a bit faster when hit, since they only have to go down

Answer 1

I saw one of the outdoor women's games clocked at 69 mph. The outdoor ball is bigger, lighter, and little softer. I'm imagine that at the men's level, at least in indoor, It would have to be 20 or 30 mph higher with harder and smaller ball.

Answer 2

probably at least 70, average im guessing is around 80-90

Answer 3

average 70
