Answer:

[tex]t=1.6\ hours[/tex]

Step-by-step explanation:

we have

[tex]t=\frac{1}{500} d[/tex]

where

t is the number of hours flying

d is the distance traveled in miles

In this problem we have

[tex]d=800\ miles[/tex]

substitute in the equation and solve for t

[tex]t=\frac{1}{500} (800)[/tex]

[tex]t=\frac{8}{5}\ hours[/tex]

[tex]t=1.6\ hours[/tex]
