walt ran 5 kilometers in 25 minutes, going eastward. what was his average velocity?
0.17 km/min east
0.2 km/min east
5 km/min east
25 km/min east

Explanation:

Step1: Recall the formula for average velocity

Average velocity \(v=\frac{\text{displacement}}{\text{time}}\)

Step2: Substitute the given values

Displacement \(d = 5\) km, time \(t=25\) min. So \(v=\frac{5}{25}\) km/min

Step3: Simplify the fraction

\(\frac{5}{25}=\frac{1}{5}=0.2\) km/min, and the direction is east.

Answer:

0.2 km/min east
