Chapter 11.2, Problem 36PPS

To determine

To Find: The average rate of the bird if it spends $250$ hours flying.

Answer to Problem 36PPS

  $20miles/hr$

Explanation of Solution

Given: A long tailed jaeger is a sea bird that can migrate $5000$ miles or more each year. The average rate in miles per hour $r$ can be given by the function $r=\frac{5000}{t}$ where $t$ the time in hours.

Given= $r=\frac{5000}{t}$

  $t$ the time in hours

Then

We have to find the rate if time is $250$ hour

Replace $t$ by $250$

  $\begin{array}{l}r=\frac{5000}{250}\\ r=20miles/hr\end{array}$

Hence, average rate of the bird is $20miles/hr$
