Mark drove 330 miles. It took him 6 hours to drive this distance. What was Mark's average speed?

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]
