Interpret distance d (miles) as proportional to time t (hours).
Alonso: d = 3t, so constant of proportionality = 3 (miles per hour).
Andy: d = 1t, so constant of proportionality = 1 (mile per hour).
Table (t in hours → d in miles)
- Alonso: 0→0, 1→3, 2→6, 3→9
- Andy: 0→0, 1→1, 2→2, 3→3
Who walked faster? Alonso (3 mi/h vs. Andy’s 1 mi/h).
