Answer:
4920
7084800
2585952000
Step-by-step explanation:
82 chirps = 1 minute
We have 60 minutes in one hour, so 82 x 60 =4920 chirps in one hour
In 24 hours we have 60x24 = 1440 minutes and in one minutes we have 4920 chirps,
Therefore 4920 x 1440 mins =7084800 chirps in one day .
There are 365 days in a year and in one day the cricket chirps 7084800, so 365 days x 7084800 = 258595200 chirps in a year
