The average speed was $40\frac{2}{3}\ \frac{miles}{hour}$

Step-by-step explanation:

we know that

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

Let

x -----> the distance in miles

y ----> the time in hours

s ----> the speed

$s=\frac{x}{y}$

we have

$x=183\ miles$

$y=4\frac{1}{2}\ hours=\frac{4*2+1}{2}=\frac{9}{2}\ hours$

substitute

$s=\frac{183}{(9/2)}$

$s=\frac{366}{9}\frac{miles}{hour}$

Convert to mixed number

$\frac{366}{9}=\frac{360}{9}+\frac{6}{9}=40\ \frac{2}{3}\frac{miles}{hour}$
