He is going faster and in a different direction during the first 10 minutes than in the last 10 minutes.
Explanation: 0–10 min: position rises from 0 to 12 km → constant speed +1.2 km/min away from home. 35–45 min (last 10 min): position is decreasing on the return → constant speed −0.8 km/min toward home. The speed is greater in the first 10 min (1.2 vs 0.8) and the direction is opposite.
