Question

zane likes to go rock climbing. zanes elevation relative to the peak of the mountain, $e$, is shown for the final 350 seconds of his climb. time in seconds is labelled $t$, as shown above. at what speed, in meters per second, did zane climb during the final 350 seconds of his climb?

Explanation:

Step1: Identify initial and final elevation

Initial elevation $E_1=- 25$ meters, final elevation $E_2 = 0$ meters.

Step2: Identify initial and final time

Initial time $t_1 = 0$ seconds, final time $t_2=350$ seconds.

Step3: Use speed formula

Speed $v=\frac{\Delta E}{\Delta t}=\frac{E_2 - E_1}{t_2 - t_1}$.
Substitute values: $v=\frac{0-(-25)}{350 - 0}=\frac{25}{350}=\frac{1}{14}\approx0.0714$ meters per second.

Answer:

$\frac{1}{14}$ meters per second
