Final answer:
Based on the information given, there seems to be an inconsistency in the question.
Step-by-step explanation:
To determine the distance between Charlotte, North Carolina and Greenville, South Carolina, we need to consider the travel times and distances of Abigail and Juan.Abigail traveled 2 1/2 hours after leaving Charlotte and had traveled 155 miles. Let's calculate her average speed: 155 miles / 2.5 hours = 62 mph.
Based on Abigail's average speed, let's determine how far she would have traveled in the first 30 minutes before Juan started his journey: 62 mph / 2 = 31 miles.
Since Abigail wanted to travel 144 miles after 2 1/2 hours, we can calculate the remaining distance she needs to travel: 144 miles - 155 miles = -11 miles.
Based on the information given, there seems to be an inconsistency in the question. It's not possible for Abigail to have traveled 155 miles and still want to travel 144 miles. Please double-check the information provided to determine the correct answer.
