Answer 1

2. On the 5th day, he jogged 38km in total.
3. He has jogged a total of 90km when he reached his house on the 10th day.
4. No, it is not possible for this way of preparing for a race to carry on like this for an indefinite period of time. This is because the athlete would eventually reach a point where he would not be able to increase the distance he jogs each day, as it would become too strenuous for him.
