To find the constant of proportionality for both Alonso and Andy, we can calculate their speeds in miles per hour.
Alonso:
- Distance: 3 miles
- Time: 1 hour
To find the speed (constant of proportionality), we use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{3 \text{ miles}}{1 \text{ hour}} = 3 \text{ miles per hour} \] So, the constant of proportionality for Alonso is 3.
Andy:
- Distance: 2 miles
- Time: 2 hours
To find Andy's speed: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{2 \text{ miles}}{2 \text{ hours}} = 1 \text{ mile per hour} \] So, the constant of proportionality for Andy is 1.
Comparison of Speeds:
- Alonso's speed: 3 miles per hour
- Andy's speed: 1 mile per hour
Who walked faster? Alonso walked faster, as he walked at a speed of 3 miles per hour, compared to Andy's 1 mile per hour.
Summary:
- Constant of proportionality for Alonso: 3
- Constant of proportionality for Andy: 1
- Who walked faster: Alonso
