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
[tex]\frac{1000}{2}=500m[/tex]
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.
