Step-by-step explanation:
3x5=15 15x.08=1.2 15+1.2=16.2
The total distance it flies, rounded to the nearest mile is: d. 1,692 miles .
<h3>Total distance</h3>
First distance= 550 miles (given)
Second distance=483 miles (given)
Now let find the third distance
Let x represent the third distance
Hence:
x/sin79 = 550/sin55
x= 659.1
Now let calculate the total distance
Total distance=550+483+659.1
Total distance= 1692.1
Total distance= 1692 miles (rounded)
Therefore the correct option is d.
