Answer:
Step-by-step explanation:
I would start by visually thinking out this problem. Or if you have time sketch it out. And don't forget the popcorn :)
Then while doing this retry the problem
Answer:
Step-by-step explanation:
{x,y,z}={−5,−6,1}
Distance=speed*time
distance traveled by plane A after 40 minutes:
distance=570×40/60=380 miles
Distance traveled by B after 40 minutes
distance=20/60×585=195 miles
Thus the distance between them will be given using cosine law:
c^2=a^2+b^2-2ab Cos C
thus we shall have:
c^2=380^2+195^2-2*380*195*cos22
c^2=45016.35275
c=212.171 miles
Thus the distance between them after 40 minutes is 212.171 miles
