Answer:
The choice of the answer is fourth option that is -61 degrees.
Therefore the temperature drop is -61°Centigrade.
Explanation:
Given:
The temperature in a town started out at 55 degrees
Start temperature = 55°Centigrade. (Initial temperature)
End of the Day = -6°Centigrade. (Final temperature)
To Find:
How far did the temperature drop?
Solution:
We will have,
![\textrm{Temperature drop}=\textrm{Final temperature}-\textrm{Initial temperature}](https://tex.z-dn.net/?f=%5Ctextrm%7BTemperature%20drop%7D%3D%5Ctextrm%7BFinal%20temperature%7D-%5Ctextrm%7BInitial%20temperature%7D)
Substituting the above values in it we get
![\textrm{Temperature drop}=-6-55\\\\\therefore \textrm{Temperature drop}=-61\° centigrade](https://tex.z-dn.net/?f=%5Ctextrm%7BTemperature%20drop%7D%3D-6-55%5C%5C%5C%5C%5Ctherefore%20%5Ctextrm%7BTemperature%20drop%7D%3D-61%5C%C2%B0%20centigrade)
Therefore the temperature drop is -61°Centigrade.
