Answer

Explanation:

Step1: Recall speed and velocity definitions

Speed is a scalar quantity, calculated as distance/time. Velocity is a vector quantity, calculated as displacement/time.

Step2: Analyze speed in both segments

In both segments, distance $d = 1500$ m and time $t=2$ minutes. Since speed $v_s=\frac{d}{t}$, the average speeds in both segments are the same because $v_{s1}=\frac{1500}{2}$ and $v_{s2}=\frac{1500}{2}$.

Step3: Analyze velocity in both segments

In the first segment, displacement is 1500 m east. In the second segment, displacement is 1500 m north. Since velocity $v_v=\frac{\vec{d}}{t}$ and the directions of displacements are different, the average velocities are different.

Answer:

C. The average speeds are the same, but the average velocities are different.
