Answer:
B
Step-by-step explanation:
Since Greg has calculated that his least or minimum speed should.be 50 miles per hour ;
Then the line starts at 50 with the starting point shaded due to the atleast notation.
Then atleast means that, Gregg may need to travel at a higher speed than 50, so the direction of the arrow moves to the right of the number line depicting a possible increase in Gregg's speed.
Therefore, the number line which best conveys Gregg's situation is B.
