Your pet cricket chirps 112 times in one minute (60.0 a). What is the temperature in degrees Fahrenheit?
A. 41.9
B. 47.0
C. 64.3
D. 74.7
Answer:
our cricket chirps 112 times in 60s
Therefore number of chirps in 13s is 
= 12.27
But we have N = T - 40
Therefore T = N+ 40
= 24.27 +40
= 64.27
64.3
So option C. is correct.
