Question

while exploring a volcano zane heard somerumbling, so he decided to climb up out of there as quicklyas he could zane's elevation relative to the edge of the inside of the volcano (in meter) as a function time (in seconds) is graphed. PLEASE HELP ME WITH THIS How long did it take Zane to reach the edge of the volcano?

Answer 1

Based on the graph you've provided, it shows Zane's elevation over time as he climbs out of the volcano. The line on the graph represents his path, and the coordinates you've mentioned, (35, 0) and (0, -25), provide us with information on his climb.

The point (35, 0) indicates that at 35 seconds, Zane reached the edge of the volcano, as his elevation relative to the edge is 0 meters. The point (0, -25) suggests that at the beginning of the observation (time 0 seconds), Zane was 25 meters below the edge of the volcano.

Therefore, it took Zane 35 seconds to reach the edge of the volcano from the time he started. There is no calculation needed as the time is directly given by the x-coordinate of the point where the line intersects the x-axis (time axis) at an elevation (y-coordinate) of 0 meters.

Answer 2

We have to find the time it took for Zane to be in the same elevation as the edge of the Volcano, that is, when his relative elevation is 0 on the graphic.

This happens at a time of 35 seconds. So:

It took Zane 35 seconds to reach the edge of the volcano.
