Chapter 1, Problem 1.76QP

Interpretation Introduction

Interpretation: The speed in miles per hour (1mi=1609m) should be calculated.

Concept Interaction:

Conversion formula:

$\begin{array}{l}1L=1d{m}^3\\ 1km=1000metre\\ 1dm=0.1metre\end{array}$

Converting hour into second can be writing as $\frac{\text{3600 s}}{\text{1 h}}$.

Converting speed of air at room temperature in second can be writing as

$\frac{\text{343}}{\text{1 s}}$.

Converting the speed in miles per hour (1mi=1609m) can be writing as $\frac{\text{1mi}}{\text{1609 m}}$

Given:

The speed of air at room temperature is about 343m/s.
