a hummingbird can flutter its wings 4,800 times per minute.
what is the frequency of wing flutters per second?
flutters/second
what is the period for one wing flutter in seconds?

f = 80  flutter/ second

T= 0.0125 sec

Explanation:

Given data:

Fluttering of wings = 4800 time per minute

Frequency of wings = ?

Period for one wing in sec = ?

Solution:

There are 60 seconds in one minute, thus frequency of wings

4800/60 = 80  flutter per second

Period:

T = 1/f

T = 1/80

T= 0.0125 sec
