Class 9th math 1.3 solution english PCTB

Question 5: The weather in Lahore was unusually warm during the summer of \(2024\). The TV news reported temperature as high as \(48^oC\). By using the formula, \(\left(^o F=\frac{9}{5} ^o C+32\right)\) find the temperature as Fahrenheit scale.

Solution:

\[
\begin{align*}
F&=\frac{9}{5} C+32\\
F&=\frac{9}{5}( 48) +32\\
F&=\frac{432}{5} +32\\
F&=86.4+32\\
F&=118.4\ ^{o} F\\
\end{align*}
