Question

The lowest recorded temperature in North America was-81°F in the Yukon Territory of Canada, and the highest recorded temperature was 134°F in Death Valley, California. Part A: Write a numerical expression that can be used to determine the difference between these two temperatures. Part B: Compute the difference between the two temperatures. The difference between the two temperatures is

Answer 1

Let,

$T_H$

be highest recorded temperature and

$T_L$

be lowest recorded temperature.

Determine the numerical expression for the difference of temperature.

$T=T_H-T_L$

Substitute -81 degree fahrenheit for T_L and 134 degree fahrenheit for T_H in the expression to obtain the difference of temperature.

$\begin{gathered} T=134^{\circ}-(-81^{\circ}) \\ =134^{\circ}+81^{\circ} \\ =215^{\circ} \end{gathered}$

So difference between the temperature is 215 degree fahrenheit.
