Question

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

Answer 1

You have to multiply 60 times 200= 12000

then multiply 12000 times 3= 36000

Answer 2

200*60=12000 (for one minute)
12000*3=36000 (for three minutes)
36000 wing beats

Hope this helps :)
