Question

An albatross is a large bird that can fly 400 kilometers in 8 hours at a constant speed. Using d for distance in kilometers and t for number of hours, an equation that represents this situation is d = 50t .

1. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? What is the relationship between these two values?


2. Write another equation that relates d and t in this context.

Answer 1

1. What are two constants of proportionality for the relationship between distance in kilometers and number of hours? What is the relationship between these two values?

The two constants of proportionality are 50 (for kph), and 50 (for distance traveled). The relationship between the two values is if either of them were to change it would affect the time. If the bird is flying at a constant rate, the distance determines the time needed to travel the distance, and if the bird were to fly at a different constant rate then the time would change as well, most likely lengthening.

2. Write another equation that relates d and t in this context.

If the albatross were to fly 90 kilometers with the variable T (# of hours) equaling 1.16667, what was the constant speed? (round your answer

to the nearest tenth)

The albatross's constant speed was: 77.1 kilometers per hour
