Question

what was the hikers average velocity during part b of the hike? hiking table distance part of hike start time ending time 4 km east a 9:00 a.m. 9:45 a.m. 6 km south b 9:45 a.m. 10:45 a.m. 4 km west c 10:45 a.m. 11:15 a.m. 6 km north d 11:15 a.m. 12:00 p.m.

Explanation:

Step1: Identify distance and time for part B

Distance = 6 km south, time from 9:45 a.m. to 10:45 a.m. is 1 hour.

Step2: Use average - velocity formula

Average velocity $v=\frac{\Delta x}{\Delta t}$, where $\Delta x$ is displacement and $\Delta t$ is time interval. Here, $\Delta x = 6$ km south and $\Delta t=1$ h. So, $v = 6$ km/h south.

Answer:

6 km/h south
