Here, the slope of orange person's graph

This implies that orange person eats daily around 10.7 bananas while its "miles jogged in day" is increasing.

The slope of the blue person's graph.

Therefore, blue person eats 5 bananas when they are jogging 8 miles per day. From this, we can say that when blue person jogs 1.6 miles per day 1 banana is eaten.

At maximum, blue person eats 2.5 bananas when they jog 24 miles while orange person eats 10.7 bananas when they hogg 24 miles.

At minimum, blue person eats 13 bananas when they jog 3.5 miles while orange person eats 10.7 bananas when they jog 3.5 miles.

We can conclude that blue person increases eating banana while they increased to jog 1.6 miles per day while orange person increases jogs per day while they are eating consistent 10.7 bananas every day.
