Answer: 1846[
Step-by-step explanation:
Given : The number of times the wings of some humming birds beat in each second = 52
If a hummingbird hovers for 35.5 seconds then , the number of times the wings of humming birds beat in 35.5 seconds will be the product of 52 and 35.5
i.e. [tex]35.5\times52=1846[/tex]
Hence, the wings of humming bird beats 1846 times in 35.5 seconds when hovering.
