Answer:
Step-by-step explanation:
we know that
To find the speed divide the total distance by the time
so
Answer:
it should take her 45 minutes to run 9 laps
Step-by-step explanation:
40/8 = 5
9*5 = 45
The solution is in parenthesis, so this means the numbers are included in the answer. Since the first number is 2, 2 is a possible answer so the circle at positive two would be solid.
The other solution is infinity, so the answers are any number to the right of the 2 on the number line.
This makes the answer: A solid circle appears at positive 2. The number line is shaded between positive 2 and positive 5.
