Use the graph showing the motion of a person over time to answer the question.

The vertical axis is labeled, position from home (km), and ranges from a 0 km to 14 km. The horizontal axis is labeled, time (minutes) and labeled from 0 minutes to 50 minutes. The graph shows a line that starts from the origin and slopes upward to 12 km at 10 minutes. The line remains at 12 km from 10 minutes to 30 minutes. The line slopes downward from 12 km to 0 km from 30 minutes to 45 minutes.

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

Reason: In the first 10 min he goes from 0 to 12 km → speed = 12/10 = 1.2 km/min away from home. During the return (30–45 min) he goes 12 km back in 15 min → speed = 12/15 = 0.8 km/min toward home, so slower and opposite direction.
