Answer 1

"He is going faster and in a different direction during the first 10 minutes than in the last 10 minutes."

Reason: The position vs time slope from 0–10 min is a steeper positive slope (faster away from home). The slope during the final descent is negative and less steep (moving toward home at a slower speed).
