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

Reason: From 0–10 min the slope = 12 km / 10 min = +1.2 km/min (away from home). In the last 10 min (35–45 min) the slope = (0 − ~8 km)/10 min ≈ −0.8 km/min (toward home). The magnitudes show he was faster in the first 10 min and the signs show opposite directions.
