Question

Complete the following table showing rise and fall of temperature at different times.

Temperature at				Final Temperature at $12$ Noon
$6A.M.$	$8A.M.$	$10A.M.$	$12NOON$
${10}^{O}C$	rise of $3^{O}C$	rise of $1^{O}C$	fall of $2^{O}C$	………………

Answer 1

Explanation:

Rise in temperature means increase in temperature or we can say we have to add to get the final temperature and fall in temperature means decrease in temperature or we can say we have to subtract to get the final temperature.

Therefore,

Final temperature at $12NOON$

$$\begin{gathered} ={10}^{O}C+3^{O}C+1^{O}C-2^{O}C \\ ={14}^{O}C-2^{O}C \\ ={12}^{O}C \end{gathered}$$

Temperature at				Final Temperature at $12NOON$
$6A.M.$	$8A.M.$	$10A.M.$	$12NOON$
${10}^{O}C$	rise of $3^{O}C$	rise of $1^{O}C$	fall of $2^{O}C$	${10}^{O}C+3^{O}C+1^{O}C-2^{O}C={12}^{O}C$
