Answer:

The speed was $61\frac{miles}{hour}$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

s------> the speed in miles per hour

d ----> the distance in miles

t ----> is the time in hours

we know that

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

we have

$d=305\ miles$

$t=5\ hours$

substitute

$s=\frac{305}{5}$

$s=61\frac{miles}{hour}$
