Answer 1

According to the temperature changes, it is found that:

• On Tuesday, the temperature at Noon was of -28.5 ºF.

• On Wednesday, the temperature at Midnight was of -5.5 ºF.

• On Thursday, the change was of -11.8 ºF.

• On Friday, the temperature at Noon was of -4.5 ºF.

What is the temperature change?

• The temperature change during a period is given by the temperature at the end of the period subtracted by the temperature at the start of the period.

On Tuesday:

• At the start of the period, the temperature was of -17.5 ºF.

• The change was of -11 ºF.

Hence:

$-11 = T_N - T_M$

$-11 = T_N + 17.5$

$T_N = -28.5$

On Tuesday, the temperature at Noon was of -28.5 ºF.

On Wednesday:

• At the end of the period, the temperature was of 10 ºF.

• The change was of 15.5 ºF.

Hence:

$15.5 = 10 - T_M$

$T_M = -5.5$

On Wednesday, the temperature at Midnight was of -5.5 ºF.

On Thursday:

• At the end of the period, the temperature was of -24 ºF.

• At the start of the period, the temperature was of -12.2 ºF.

Hence:

$C = -24 - (-12.2) = -24 + 12.2 = -11.8$

On Thursday, the change was of -11.8 ºF.

On Friday:

• At the start of the period, the temperature was of -21.8 ºF.

• The change was of 17.3 ºF.

Hence:

$17.3 = T_N - T_M$

$17.3 = T_N + 21.8$

$T_M = -4.5$

On Friday, the temperature at Noon was of -4.5 ºF.
