Answer:

The average speed is $\frac{3}{35}\frac{ft}{min}$

Step-by-step explanation:

we know that

To find out the average speed divide the distance by the time

Let

s -----> average speed

d -----> the distance in feet

t ----> the time in minutes

$s=\frac{d}{t}$

we have

$d=6\ ft$

$t=70\ min$

substitute

$s=\frac{6}{70}\frac{ft}{min}$

Simplify

$s=\frac{3}{35}\frac{ft}{min}$

Civil an airport, a factory, and a shopping center are at the vertices of a right triangle formed by three highways. the airport

Answer:

<em>The shortest possible length for the service road is 2.88 miles.</em>

Step-by-step explanation:

According to the below diagram, $A, B$ and $C$ are the positions of airport, shopping center and factory respectively.

Given that, $AB= 3.6 miles, BC= 4.8 miles$ and $AC= 6.0 miles$

In right triangle $ABC$

$tan(\angle ACB)=\frac{AB}{BC} \\ \\ tan(\angle ACB)= \frac{3.6}{4.8}=0.75\\ \\ \angle ACB= tan^-^1(0.75)=36.8698.... degree$

The shortest possible length for the service road from the shopping center to the highway that connects the airport and factory is $BD$ .

That means, $\triangle BCD$ is also a right triangle in which $\angle BDC=90\°$ , Hypotenuse $(BC)= 4.8$ miles and $BD$ is the opposite side in respect of $\angle DCB$ or $\angle ACB$ .

Now in right triangle $BCD$

$Sin(\angle ACB)=\frac{BD}{BC}\\ \\ Sin(36.8698...)=\frac{BD}{4.8}\\ \\ BD=4.8*Sin(36.8698...)=2.88$

So, the shortest possible length for the service road is 2.88 miles.
