Answer:
4,687.2 flaps
Step-by-step explanation:
#We calculate the number of flaps per second:
[tex]Flaps/Second=\frac{60}{2}\\\\=30 \ flaps[/tex]
#Since one minute has 60 seconds, we will multiply our time by 60 seconds and then by flaps/second:
[tex]Flaps=Rate \times time\\\\=30\times 2.604\times 60\\\\=4687.2\ flaps[/tex]
Hence, the bird makes 4,687.2 flaps in 2.604 minutes.
