Answer:
3 meters
Explanation:
Given that,
Fido is initially standing near the person's feet. Initially, he jogs 10 meters in a straight line to retrieve a stick and carries it 7 m back toward the person before lying on the ground to chew on the stick.
Initially, he covers 10 meters of distance then it comes towards the person and covers 7 meters in front of the person.
It is clear that he is at a distance of 10 meters - 7 meters = 3 meters
