Answer:
b. 2,200 miles
Step-by-step explanation:
Given:
The speed of the plane is,

Time taken by the plane is,

Now, distance traveled by the plane is given as the product of speed of the plane and the time taken by the plane. Therefore, the distance is given as:
Distance = Speed
Time taken
Distance =

Plug in 550 for 's' and 4 for 't'. Solve for distance.
Distance =

Therefore, the distance traveled by the plane traveling at 550 mi/h in 4 hours is 2,200 miles.
