Chapter 1.1, Problem 65E

To determine

To calculate: To complete the statement and round to the nearest hundredth (if required)

Answer to Problem 65E

  $\frac{8km}{\min }\approx \frac{29.82mi}{h}$

Explanation of Solution

Given: Statement is $\frac{8km}{\min }\approx \frac{\_\_\_mi}{h}$

Formula Used:

Conversions are

  $\begin{array}{l}1km=0.621miles\\ 1h=60\mathrm{mins}\end{array}$

Calculation:

Given that $\frac{8km}{\min }\approx \frac{\_\_\_mi}{h}$

Converting km/min to miles/hr:

  $\begin{array}{l}\frac{8km}{\min }\approx \frac{8\times 0.621mi}{\raisebox{1ex}{$1$}\!\left/ \!\raisebox{-1ex}{$60$}\right.h}\\ \frac{8km}{\min }\approx \frac{4.970\times 60mi}{h}\\ \frac{8km}{\min }\approx \frac{29.82mi}{h}\end{array}$

Conclusion:

Hence, $\frac{8km}{\min }\approx \frac{29.82mi}{h}$
