Answer:
(a) See attachment for number line
(b) 1/3 of the total distance is left
Explanation:
Given
Let A represent Aarron's turtle and R represents Rodolfo's turtle.
From the question
--- Position
R = Finished the race
Solving (a): Number line showing their positions
Because R finished the race, its position will be at the end of the number line
While
A's position will be at 4/6th position
Let the interval of the number line be 6.
See attachment for number line
Solving (b): What's left of A's distance
The distance left will be calculated using
Hence, 1/3 of the total distance is left
