Velocity is the speed and direction combined.
So, the two jets both are going at the same speed.
But they are going in different directions, so their velocities are different.
The answer is Convoluted endoplasmic reticulum
Answer:
a) 0 m/s
b) 4 m/s
Explanation:
The average velocity would end up being 0 because it is displacement over time and the displacement here is 0. However, speed is total distance over time which here is 400/100 so it is 4.
