Question

a skydiver jumps out of a plane from a certain height. the graph below shows their height h in meters after t seconds. how long is the skydiver in the air?

Explanation:

Step1: Identify key points on graph

The skydiver starts at $t = 0$ and lands when $h=0$. The graph shows the point $(23,0)$ where the height $h = 0$ meters.

Step2: Determine time in air

The time $t$ when the skydiver lands is the time they are in the air. From the point $(23,0)$, the time $t = 23$ seconds.

Answer:

23 seconds
