Answer:
the seed of the sound in the air is 343.3 m/s
Explanation:
The computation of the speed of the sound in the air is shown below:
As we know that
Speed = Distance divided by Time
So, here speed be 515m
And, the time is 1.50 second
So, the speed of the sound is
= 515m divided by 1.50 seconds
= 343.3 m/s
hence, the speed of the sound in the air is 343.3 m/s
Answer:
So airplane will be 1324.9453 m apart after 2.9 hour
Explanation:
So if we draw the vectors of a 2d graph we see that the difference in angles is = 83 - 44.3 =
Distance traveled by first plane = 730×2.9 = 2117 m
And distance traveled by second plane = 590×2.9 = 1711 m
We represent these distances as two sides of the triangle, and the distance between the planes as the side opposing the angle 38.7.
Using the law of cosine, representing the distance between the planes, we see that:
d = 1324.9453 m
I think b is the answer but im not 100% sure
