Question

A diver stands on a platform 15 feet above a lake. He does a dive off the platform and lands in the water below. His height (h) above the lake after x seconds is shown on the graph below. After how many seconds did the diver land in the water?

Answer 1

The diver lands on water after 3 seconds.

`3\text{ seconds}`

Step-by-step explanation:

Given that the diver stands on a platform 15 ft above a lake.

As shown on the graph, at x=0, height h equals 15 ft.

The diver lands on water at h equals zero.

The time at h=0 is x=3 seconds.

Therefore, the time taken for the diver to land in water is;

`\begin{gathered} x=3-0 \\ x=3\text{ seconds} \end{gathered}`
