Final answer:
Molly lives 15 blocks from the restaurant and walks at 0.5 blocks per minute, taking 30 minutes to arrive. Without Riley's graph, we can't compare their distances or speeds to determine who lives closer, walks faster, or arrives first at the restaurant; any answer would be hypothetical.
Step-by-step explanation:
Molly and Riley are planning to meet at a restaurant. Molly lives 15 blocks from the restaurant and walks at 0.5 blocks per minute. This means it will take her 30 minutes to reach the restaurant. Unfortunately, without Riley's graph, we can't compare Riley's distance and speed directly with Molly's data. However, we can use the information provided in different scenarios to create hypothetical answers.
If Riley walked faster than 0.5 blocks per minute or lives less than 15 blocks away, we could then say:
- Lives closest to the restaurant: Molly or Riley (depending on Riley's starting distance)
- The faster walker: Riley (if Riley's speed exceeds 0.5 blocks per minute)
- First to arrive: Riley (if Riley walks faster or has less distance to cover)
Without Riley's exact speed and starting distance, we can't finalize the answers to the question. Therefore, with the data at hand, we can only speculate based on Molly's fixed distance and speed.
