Final answer:
Lily has 12 more miles to walk. As she walks at a speed of 3 miles per hour, it will take her 4 hours to reach her total goal of 14 miles.
Step-by-step explanation:
The subject of this question is in the area of mathematics, specifically, it is about understanding how to solve problems related to distance, speed, and time. Lily has already walked 2 miles, but she wants to walk a total of 14 miles. This means Lily has 14 - 2 = 12 more miles to walk to reach her goal. Lily plans to walk at a speed of 3 miles per hour, so, to find out how many hours it will take to walk the remaining 12 miles, we divide the distance she has yet to walk (12 miles) by her speed (3 miles per hour). This gives us 12 ÷ 3 = 4 hours. Therefore, it will take Lily 4 more hours to reach her goal of walking 14 miles.
