Answer : The temperature on the Fahrenheit scale was, $113^oF$

Explanation :

The conversion used for the temperature from degree centigrade to Fahrenheit is:

$^oF=(^oC\times \frac{9}{5})+32$

where,

$^oF$ = temperature in Fahrenheit

$^oC$ = temperature in centigrade

As we are given the temperature in degree centigrade is, 45

Now we have to determine the temperature in Fahrenheit.

$^oF=(45^oC\times \frac{9}{5})+32$

$^oF=113$

Therefore, the temperature on the Fahrenheit scale was, $113^oF$
