Chapter SH, Problem 9.3MPS

To determine

To calculate: No. of times more people drove than walked to work.

Answer to Problem 9.3MPS

No. of times more people drove than walked to work is ${10}^2$ .

Explanation of Solution

Given information:

  

Calculation:

From the given diagram it is observed that,

The number of people who drive to work is equals to ${10}^5$ .

The number of people who walk to work is equals to ${10}^3$ .

The number of times is equals to the ratio of the number of people drive to the people walk.

The number of times $=\frac{{10}^5}{{10}^3}$

According to the quotient of property rule, one can subtract the power in denominator from the power in the numerator.

After simplifying,

  $\begin{array}{l}=\frac{{10}^5}{{10}^3}\\ ={10}^{5-3}\\ ={10}^2\end{array}$

Thus, ${10}^2$ times as many people drive than walk to work.
