(a)

Answer to Problem 24PPS
Explanation of Solution
Given:Abigail left Charlotte, North Carolina, 30 minutes before Juan to travel to Greenville, South Carolina. Two and a half hours after Abigail left, she had traveled 155 miles and Juan had traveled 144 miles.
First find the rate of Abigail and Juan.
According to given info,
In 2 and half hours Abigail traveled 155 miles.
Therefore, the rate of Abigail is 62 mph.
In 2 and half hours Juan traveled 144 miles.
Therefore, the rate of Juan is 57.6 mph.
Now make table for each person traveled after 1, 2, 3 and 4.
(b)
To Find: The speed in miles per hour.
(b)

Answer to Problem 24PPS
No intersection point
Explanation of Solution
Given:The tabular form of distance traveled by Juan and Abigail.
Now plot the points on graph and join the points.
No, two lines are not intersect to each other.
Hence, there are no intersection points of Abigail and Juan.
