To answer the questions based on the provided data:
a. To calculate the average distance traveled per minute, we can find the total distance traveled and divide it by the total time:
Total distance (y) = 40 + 25 + 35 + 10 + 45 = 155 meters
Total time (x) = 8 + 5 + 7 + 2 + 9 = 31 minutes
Average distance traveled per minute = Total distance / Total time = 155 / 31 ≈ 5 meters per minute
Response for part a: 5 meters are traveled.
b. To express the relationship between x (time in minutes) and y (distance in meters), we can use the average speed calculated earlier. The relationship can be modeled as:
y = 5x
Response for part b: y = 5x.
