To determine if the relationship is proportional, we need to see if there is a constant ratio between the time spent walking and the number of calories burned.
Let's calculate the ratios for each pair of values:
For 20 minutes of walking: 20 minutes / 100 calories = 0.2 minutes/calorie
For 30 minutes of walking: 30 minutes / 150 calories = 0.2 minutes/calorie
For 40 minutes of walking: 40 minutes / 200 calories = 0.2 minutes/calorie
For 60 minutes of walking: 60 minutes / 300 calories = 0.2 minutes/calorie
For 80 minutes of walking: 80 minutes / 400 calories = 0.2 minutes/calorie
Since the ratio is consistently 0.2 minutes/calorie for each pair, we can conclude that the relationship between the time spent walking and the number of calories burned is proportional.
