If the starting temperature of the water is 185°F, what was the temperature in Celsius?

If the starting temperature of the water is 185°F, what was the temperature in Celsius?

• A. 80°C
• B. 75°C
• C. 85°C
• D. 90°C

Answer: (C)

To convert a temperature from Fahrenheit to Celsius, you can use the formula: \[ C = \frac{(F - 32) \times 5}{9} \] where \( F \) is the temperature in Fahrenheit and \( C \) is the temperature in Celsius. In this case, you are starting with a temperature of 185°F. Plugging that into the formula gives: \[ C = \frac{(185 - 32) \times 5}{9} \] First, subtract 32 from 185: \[ 185 - 32 = 153 \] Next, multiply 153 by 5: \[ 153 \times 5 = 765 \] Finally, divide by 9 to get the temperature in Celsius: \[ C = \frac{765}{9} = 85 \] Thus, 185°F is equivalent to 85°C. This calculation confirms that the correct conversion yields an answer of 85°C, making it the right choice.

To convert a temperature from Fahrenheit to Celsius, you can use the formula:

[

C = \frac{(F - 32) \times 5}{9}

]

where ( F ) is the temperature in Fahrenheit and ( C ) is the temperature in Celsius.

In this case, you are starting with a temperature of 185°F. Plugging that into the formula gives:

[

C = \frac{(185 - 32) \times 5}{9}

]

First, subtract 32 from 185:

[

185 - 32 = 153

]

Next, multiply 153 by 5:

[

153 \times 5 = 765

]

Finally, divide by 9 to get the temperature in Celsius:

[

C = \frac{765}{9} = 85

]

Thus, 185°F is equivalent to 85°C. This calculation confirms that the correct conversion yields an answer of 85°C, making it the right choice.
