Answer:
<h2>Sam cycled fast, at a rate of 10 miles per hour.</h2>
Step-by-step explanation:
To solve this problem we have to find the slope of each case. The definition of a slope is:

Where
is the first point, and
is the second point.
Let's find each slope.
<h3>Sam.</h3>
Let's use the points
and 
Applying the definition of the slope, we have:

This relation means that Sam cycled 10 miles per hour.
<h3>Bobby.</h3>
Let's use the points
and 

Bobby cycled 9 miles per hour.
Therefore, according to these ratios, Sam cycled fast, at a rate of 10 miles per hour.
