Question

The ruby-throated hummingbird has a wing beat of about 200 beats per second. About how many wing beats would a hummingbird have in 3 minutes

Answer 1

When you multiply 200 by 60, you get 12000. and you multiply that by 3 and you get 36000. so in 3 minutes it'd be 36000

Answer 2

So,
To get how many wingbeats per minute,
200x60=12000 because there are 60 seconds in a minute
To get how many in 3 minutes,
12000x3=36000

Hope I helped!
