Chapter 6.8, Problem 35S

To determine

To Solve: The equation $\frac{2}{9.4}=\frac{0.2}{v}$

Answer to Problem 35S

  $v=0.94$

Explanation of Solution

Given information:

The equation $\frac{2}{9.4}=\frac{0.2}{v}$

Concept and Formula Used:

To solve the equation bring variable to one side and constant to other side and use cross multiplication.

Calculation:

The given equation is $\frac{2}{9.4}=\frac{0.2}{v}$

Cross multiply

  $\begin{array}{l}\frac{2}{9.4}=\frac{0.2}{v}\\ 2\times v=0.2\times 9.4\\ 2v=1.88\\ \text{Divide both side by 2}\\ \frac{2v}{2}=\frac{1.88}{2}\\ 1v=0.94\\ \text{or }v=0.94\end{array}$

Conclusion:

  $v=0.94$
