Explanation:
The relationship between time, speed, and distance is ...
distance = speed · time
Stephanie wants her first break before 65 miles, so the time until the break will satisfy the inequality ...
10t < 65 . . . break before 65 miles
t < 6.5 . . . . . divide by 10
On a graph, values less than 6.5 will appear shaded to the left of that point. Since 6.5 is not included in the solution set, the dot at that point is an open circle.
