Answer:
Alexandria can choose any distance not more than 130 miles from her house to the park.
Explanation:
Let Alexandria takes time 't' hours to walk from home to the park and distance between park and home is 'x' miles.
If she averages 65 miles per hour "to and fro" from her home to the park then the inequality that will represent this situation will be
2x ≤ 65t [ Distance = Speed × time ]
If she wants to hike for 2 hours and maximum time spent to reach the park is 6 hours
Then the maximum time spent by her to reach the park from her home should be = 6 - 2 = 4 hours.
By placing the value of t = 4 in the inequality
2x ≤ (65×4)
2x ≤ 260
x ≤ 130
Therefore, Alexandria can choose any distance not more than 130 miles from her house to the park.
