Answer:
7 km and 3 km
Explanation:
According to the given question, it's a linear motion.
AB = 5 km and BC = 2 km
5 km
<---------------------------->
A C B
<------------><------------>
3 km 2 km
From the figure we can see that AC= 3 km
And we are asked to find the total distance and magnitude of displacement.
Now,
Total distance = (A to B) + (B to C)
= 5+2 = 7 km
Magnitude of displacement = AC = 3 km
As the initial position is A and final position is C.
One thing to note here is that, not always magnitude of displacement is equal to distance.
