Answer:
The Mark's average speed was [tex]55\frac{miles}{hour}[/tex]
Step-by-step explanation:
we know that
To find out the average speed, divide the total distance by the total time
Let
s -----> the average speed in miles per hours
x ----> the total distance in miles
y ----> the total time in hours
[tex]s=\frac{x}{y}[/tex]
we have
[tex]x=330\ miles[/tex]
[tex]y=6\ hours[/tex]
substitute
[tex]s=\frac{330}{6}=55\frac{miles}{hour}[/tex]
