Answer:

1533.8

Explanation:

To solve this problem, we can use the formula:

distance = speed × time

First, we need to convert the direction of 224° to a component of motion. We can do this using trigonometry:

cos(224°) = -0.766

sin(224°) = -0.643

The negative sign indicates that the plane is traveling south and west.

Next, we can calculate the distance traveled:

distance = speed × time

distance = 445 mph × 4.5 hours

distance = 2002.5 miles

Finally, we can calculate the distance west:

distance west = distance × cos(224°)

distance west = 2002.5 miles × (-0.766)

distance west = -1533.8 miles

We get a negative distance west because the plane is traveling west but also south, so we can say that the plane is 1533.8 miles west-southwest of Providence (rounded to the nearest tenth).
