distance part of hike start time ending time
6 km east a 8:00 a.m. 9:00 a.m.
4 km south b 9:00 a.m. 9:45 a.m.
6 km west c 9:45 a.m. 10:45 a.m.
8 km north d 10:45 a.m. 12:30 p.m.

Explanation:

Step1: Identify distance and time for part C

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

Step2: Use velocity formula

Velocity $v=\frac{\text{displacement}}{\text{time}}$. Here displacement is 6 km west and time $t = 1$ h. So $v=\frac{6\text{ km west}}{1\text{ h}}=6$ km/h west.

Answer:

6 km/h west
