Chapter SH, Problem 6.3.10EP

To determine

To calculate: The acres that were destroyed per hour.

Answer to Problem 6.3.10EP

The required acres that were destroyed is 3,333.33 acres per hour.

Explanation of Solution

Given information:

The rate of wildfire destroyed = 240,000 acres in 3 days

Calculation:

The given rate can be expressed in fraction as,

  $\frac{240,000\text{acres}}{3\text{days}}$

It is known that 1 day = 24 hours

To find the acres that were destroyed per hour, multiply the above fraction by $\frac{1\text{day}}{24\text{hours}}$ and simplify.

  $\begin{array}{c}\frac{{}^{10,000}\cancel{240,000}\text{acres}}{3\cancel{\text{day}}}\times \frac{1\cancel{\text{day}}}{\cancel{24}\text{hours}}=\frac{10,000}{3}\text{acres}/\text{hour}\\ \approx 3,333.33\text{acre}\text{per}\text{hour}\end{array}$

Hence, the required acres that were destroyed is 3,333.33 acres per hour.
