Question

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 velocity

Velocity is defined as the displacement divided by the time taken. The formula is \( v=\frac{d}{t} \), where \( v \) is velocity, \( d \) is displacement, and \( t \) is time.

Step2: Identify the given values

The displacement \( d = 5\) kilometers (east) and the time \( t=25\) minutes.

Step3: Calculate the velocity

Substitute the values into the formula: \( v=\frac{5\space km}{25\space min} = 0.2\space km/min\) (east, since displacement is eastward).

Answer:

0.2 km/min east
