Let v is the speed of the light wave. It is given by :
So, the speed of the light wave is . Hence, this is the required solution.
Answer:
The direction will be and the distance 250.75km.
Explanation:
Let's say A is the displacement vector which represents the first 170km and B the one for the next 230km. Then the components of these vector will be:
The vector which point from the origin to the final position of the plane will be R=A+B. We sum components on <em>x </em>and <em>y </em>independetly (vector property):
If is the direction of R then:
⇒
⇒
.
The distance will be given by the magnitud of the vector R:
⇒
.
