Chapter 6.3, Problem 1CYU

To determine

The rainforest destroyed per day.

Answer to Problem 1CYU

  $\text{28,800 acres}$

Explanation of Solution

Given information:

About $20$ acres of rainforest are destroyed each minute in Brazil.

Formula used:

A day contains 24 hours and hours and minutes are related to each other by a mathematical equation which is expressed as,

  $1\text{hour}=60\text{minutes}$

Calculation:

Consider the provided statement “About $20$ acres of rainforest are destroyed each minute in Brazil.”

Recall that a day contains $24$ hours and conversion rule that $1\text{hour}=60\text{minutes}$ .

So, $24$ hours is evaluated as when $24$ is multiplied by $60$ .

Therefore, $24$ hours is,

  $\begin{array}{c}1\text{hr}=60\min \\ 24\text{hrs}=\left(24\times 60\right)\min \\ 24\text{hrs}=1440\min \end{array}$

Now, to calculate how much acres of rainforest are destroyed per minute,

It will be evaluated as when $20$ is multiplied by $1440$ .

Therefore, in one day rainforest destroyed are,

  $\begin{array}{c}1\min =20\text{acres}\\ 1440\min =\left(1440\times 20\right)\text{acres}\\ 1440\min =28,800\text{acres}\end{array}$

Hence, rainforest destroyed per day are $\text{28,800 acres}$ .
