#36,000# beats. This can also be written as #3.6*10^4# beats

Explanation:

The key to this is working out how many seconds there are in 3 minutes.
As there are #60# seconds in a minute, 3 minutes is #3*60 = 180# seconds.

The hummingbird has #200 beats per second.

In 3 minutes there will be #200*180 =36000 # beats
