Question

The temperature at 8 AM was 43°F. AT IAM the temperature was 5°F warmer. At 8PM the temperature was 12°F colder than at I AM What was the temperature at 8PM?

Answer 1

The temperature at 11AM is 5 degree fahrenheit warmer that that at 8 AM, so temperature at 11 AM is,

$\begin{gathered} T=43^{\circ}F+5^{\circ}F \\ =48^{\circ}F \end{gathered}$

At 8 PM, the temperature was 12 degree fahrenheit colder than that at 11 AM. So temperature at 8 PM is,

$\begin{gathered} T^{\prime}=48^{\circ}F-12^{\circ}F \\ =36^{\circ}F \end{gathered}$
