Sagot :
The average velocity of the journey is determined as 7.4 m/s.
What is average velocity?
The average velocity of an object is the change in displacement of an object with time.
We will analyze the three stage motion as follows;
1. first stage
speed, v = 12 m / s, t = 1.5 min = 90 s
the distance traveled, s = v x t
s= 12 x 90
s = 1080 m
2. second stage
stop (v = 0) so that s = 0 and t = 3.5 min = 210 s
3. third stage
move with v = 15 m / s and t = 2.5 min = 150 s
the distance traveled, s = v x t
s = 15 x 150
s = 2250 m
Total displacement = 2250 + 1080 = 3330 m
average velocity = total displacement / time taken
average velocity = 3330/450
average velocity = 7.4 m / s
Thus, the average velocity of the journey is determined as 7.4 m/s.
