Question

Help!! need answer now! Michelle jumps from a plane at an altitude of 1000 m. After 10 seconds her parachute opens. The graph shows the relationship between her altitude and time. How long does it take for her to be half way between the plane and the ground?


Answer 1

Answer:

1 minute.

Step-by-step explanation:

When the distance is 500, the time is 1 minute.

Answer 2

Answer:

Option 2 - 1 minute

Step-by-step explanation:

Given : Michelle jumps from a plane at an altitude of 1000 m. After 10 seconds her parachute opens. The graph shows the relationship between her altitude and time.

To find : How long does it take for her to be half way between the plane and the ground?

Solution :

Total altitude is 1000 m.

Half of the way between plane and the ground is

$\frac{1000}{2}=500m$    

Now, Referring the graph given  at an altitude of 500 m the line passes at time t=1 min.

Therefore, The time taken to be half way between the plane and the ground is 1 min.

Hence, Option 2 is correct.

Refer the attached figure below.
