Answer:
1,680
Step-by-step explanation:
We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.
420/30
42/3
14 beats/second
Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.
14 * 120
(14 * 12) * 10
168 * 10
1,680 beats
