tino4ka555 [31]

Answer: Celsius scale

Step-by-step 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)(\frac{9}{5})+32=86\°F
