Final answer:
The question about Sara's distance from the park cannot be answered with the provided information. Instead, we discussed the problem-solving steps for calculating the area of a park on a scale map, determining time from speed and distance, and understanding displacement in a hiking scenario.
Step-by-step explanation:
The question asked does not provide enough information to determine how far Sara lives from the park. To answer this, we would need specific details about Sara's location in relation to the park or some context related to the distances mentioned in the question. None of the provided scenarios involving Jill's flyer delivery or Cassie's walk directly relate to Sara's distance from the park.
Problem Solving with Map Scale
For question 15, to find the area of the park in square feet on a scale drawing where 0.5 inches = 1 mile, we calculate the actual area represented by the dimensions 0.5 inch by 1.5 inches. First, we convert the dimensions from inches on the drawing to miles using the scale provided, then convert miles to feet (1 mile = 5280 feet). The area of the park in square feet would be the product of these converted dimensions.
Calculating Time from Speed and Distance
In relation to question 9, to calculate the time Cassie took to walk to her friend's house, we use the formula time = distance/speed. Given the distance is 205 meters and speed is 1.40 meters per second, the time in seconds is the distance divided by the speed. To convert seconds to minutes, we divide by 60.
Understanding Displacement
The final displacement in question 4 for each camper would be the straight-line distance from their cabin to the spot on the lake. This is not necessarily equal to the distance traveled along each path. Displacement is a vector quantity represented by the straight line and direction from the starting point to the final position.
