Answer:
180m to the east
Explanation:
Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.
point A runs 150m east,
70m west
100m east
150m
--------------------------------------------------------→
70m
←---------------------
100m
-----------------------------------→
The displacement of the athlete = 150 - 80 + 100 = 180m to the east
From that ragged, motley list of statements, only 'C' is true.

Distance divided by time.
Answer:
4.55 m/s
Explanation:
The frequency is defined as the number of rotations in one second
So, f = 2.03 Hz
r = 0.357 m
The tangential speed is
v = r ω = r x 2 x 3.14 x f = 0.357 x 2 x 3.14 x 2.03 = 4.55 m/s
