Chapter 13.7, Problem 30SR

To determine

The ending temperature of Browning, Montana is to be estimated.

Answer to Problem 30SR

The ending temperature of Browning, Montana is $-56°F$

Explanation of Solution

Given:

  $\begin{array}{l}m=-10°F/hr\\ x=10hrs.\end{array}$

Concept Used:

Slope intercept form is given by the following expression:

  $y=mx+b$

Where,

Ending temperature: $y$

Rate of increase or decrease: $\pm m$

No. of times this process must continue: $x$

Starting temperature: $b$

Calculation:

The ending temperature of Browning, Montana is calculated as:

  $\begin{array}{l}y=mx+b\\ y=-10\times 10+44\\ y=-56°F\end{array}$

Conclusion:

Hence, the ending temperature of Browning, Montanais $y=-56°F$ .
