On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, [tex]d[/tex], to the number of hours flying, [tex]t[/tex], is [tex]t = \frac{1}{500} d[/tex].
How long will it take the airplane to travel 800 miles?
Each table represents a proportional relationship. For each, find the constant of proportionality.
