Answer:
17
Step-by-step explanation:
500/2 = 250
250/15 = 16.6 repeated
If you round 16.6, you get 17, and it better to have too many, than not enough.
In one hour, the trains will be 95 miles apart.
504 / 95 = 5.31 hours.
It will take 5.31 hours for the two trains to be 504 miles apart.
Answer:
4.68° south east 317.36 km
Step-by-step explanation:
We can find the angle between the two distances (vectors) because according to the diagram, we can draw two right triangles between them.
The complement of the 36 degree angle is 54 (90-36=54), and the complement of the 68 angle is 22, (90-68=22) the sum of 22 and 54 is 76. So the angle between the two distances is 76.
Then we apply the cosine law
then we apply the sin law
and because in any triangle, the sum of the inside angles is equal to 180
180= 76+C+(68+Y)
y=180-76-C-68
So the emergency plane has to travel 317.36 km, 4.68° southeast.
