Question

Of the following approximate conversions of Celsius into Fahrenheit, which is most accurate?

Answer 1

Answer:

option (b) is more accurate.

Step-by-step explanation:

Given some temperature in °C and °F.

We have to check out of given option which is most accurate conversion.

We check of conversion one by one ,

We know the relationship between the temperature in degrees Celsius, C, and degrees Fahrenheit is

$F=\frac{9}{5}C+32$

1) 24°C and 75.9°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

$F=\frac{9}{5}C+32$

$F=\frac{9}{5}(24)+32$

$F=75.2$

2) 2°C and 35.8°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

$F=\frac{9}{5}C+32$

$F=\frac{9}{5}(2)+32$

$F=35.6$

3) 34°C and 92.7°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

$F=\frac{9}{5}C+32$

$F=\frac{9}{5}(34)+32$

$F=93.2$

4) 13°C and 55°F

We substitute the values of degree Celsius and find for degree Fahrenheit.

$F=\frac{9}{5}C+32$

$F=\frac{9}{5}(13)+32$

$F=55.4$

Thus, out of given options , option (b) is more accurate.
