Answer:
4.83 hours
Explanation:
We can solve the problem by using the definition of average speed for a uniform motion:
[tex]v=\frac{d}{t}[/tex]
where
d is the distance covered
t is the time taken
v is the average speed
For the plane in this problem, we know:
d = 2780 mi is the distance
v = 575 mph is the speed
Solving for t, we find how much time the flight takes:
[tex]t=\frac{d}{v}=\frac{2780}{575}=4.83 h[/tex]
