Question

Ms. Aaron's is on a plane headed West at 930 km/hr. She walks towards the back of the plane at 10 km/hr. 1. What is the speed and direction of the plane if Mrs. Aarons is the point of reference? 2. What is the speed of Mrs. Aarons using the ground as a frame of reference? 3. Another plane is traveling the same direction as the first at 930 km/hr. What is the speed of Mrs. Aarons relative to the other plane? 4. Another plane is traveling East at 750 km/hr. What is the speed and direction of the first plane using the second as a frame of reference. 5. What is the velocity of Mrs. Aarons relative to the other plane in problem #4?

Answer 1

See below in bold.

Step-by-step explanation:

1. That would be 930 -10 = 920 km/hr due West.

2.The speed of Mrs Aarons relative to the ground is 930 - 10 = 920 km/hr.

3. This would be 10 km due East.

4.This is 930 - 750 = 180 km/hr West.
