Chapter 6.4, Problem 28E

To determine

To find:thebirds speed in miles per hour when birds flies $266miles$ in $19hours$ .

Answer to Problem 28E

the birds speed in miles per hour is $14$ when birds flies $266miles$ in $19hours$ .

Explanation of Solution

Given information : the speedprovided in the question,

  $266miles$ in $19hours$ .

Formula used:

  $speed=\frac{dis\tan ce}{time}$

Calculation: to find the speed, find the ratio of distance with time ,

  $\begin{array}{l}speed=\frac{dis\tan ce}{time}\\ speed=\frac{266}{19}\text{ [substitue]}\\ speed=14miles\text{ per hour [divide]}\end{array}$

Hence,the birds speed in miles per hour is $14$ when birds flies $266miles$ in $19hours$ .
