Answer:
Distance is 15 meters.
Step-by-step explanation:
It is given that,
Velocity with respect to the x frame, v = 5 m/s
We need to find the position in each frame after 3 seconds have passed.
Distance covered is calculated by the product of velocity and time taken. It is given by :


d = 15 meters
So, after 3 seconds the position in each frame is 15 meters from origin. Hence, this is the required solution.
