What is the average time interval between heartbeats?
what is the average time between a hummingbird flaps its wing?

time between beats= 1/heartrate
so if your heart pitty pats at 80 beats/min, then time= 1/80 min or 60/80 sec
Doesn't a hummingbird flap its wings at about... http://hypertextbook.com/facts/2000/MarkLevin.shtml
