An albatross is 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 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?
