Question

On a hot summer day, Jen is in a foreign country. She wonders which

temperature scale is used there, Celsius or Fahrenheit. Thermometers on
two local banks read 30. Since 30 Fahrenheit is below freezing,
o which scale is being used?​

Answer 1

Answer: Celsius scale

Explanation:

Fahrenheit scale is established from the freezing and boiling temperatures of water, which are:

Freezing temperature of water:
`32\°F`

Boiling temperature of water:
`212\°F`

Which means that all temperatures below
`32\°F` are below the freezing temperature of water. Therefore, if Jen is in the Summer season, which is characterized by high temperatures, it is incoherent to think that the thermometer is using the Farenheit scale.

Now,
`30\°C` is in accordance with the high temperatures recorded in the summer season.

If we want to know how much
`30\°C` is in Farenheits, we must use the following conversion formula:

`(30\°C)((9)/(5))+32=86\°F`
