To analyze the given equation \( y = 2.5x + 5 \), where:
- \( x \) is the number of miles,
- \( y \) is the total time in minutes,
we can derive the following insights:
- The equation suggests that there is a constant time of 5 minutes before travel begins (time to prepare the food).
- The term \( 2.5x \) implies it takes 2.5 minutes for every mile traveled.
Given this model, we can evaluate the statements:
- On average, it takes the delivery person 5 minutes to travel 1 mile. - Incorrect: It actually takes 2.5 minutes per mile.
- On average, the delivery person travels 2.5 miles every 1 minute. - Incorrect: The delivery person travels 1 mile in 2.5 minutes, not the other way around.
- The average amount of time the shop needs to prepare the food for delivery is 5 minutes. - Correct: This is the constant term in the equation.
- The average amount of time the shop needs to prepare the food for delivery is 2.5 minutes. - Incorrect: As above, the preparation time is 5 minutes.
- On average, it takes the delivery person 2.5 minutes to travel 1 mile. - Correct: This comes directly from the coefficient of \( x \).
- On average, the delivery person travels 5 miles every 1 minute. - Incorrect: This is the opposite of what the equation indicates.
Therefore, the two correct statements according to the model are:
- The average amount of time the shop needs to prepare the food for delivery is 5 minutes.
- On average, it takes the delivery person 2.5 minutes to travel 1 mile.
