Final answer:
The constant of proportionality in this situation is 80 miles per hour, which means that for every hour the eagle flies, it will cover a distance of 80 miles.
Step-by-step explanation:
- Distance: 480 miles
Time: 6 hours
Speed = Distance / Time
Speed = 480 miles / 6 hours
Speed = 80 miles per hour - The constant of proportionality in this situation is 80 miles per hour. This means that for every hour the eagle flies, it will cover a distance of 80 miles.
