Given :
A bird flies 6 km east, then 4 km west.
To Find :
the total distance traveled and displacement after this flight.
Solution :
a)
We know , total distance is the amount of how much ground an object has covered .
Distance = 6+4 km = 10 km .
b )
Displacement is the shortest distance from one point to another .
Now , here the object first move 6 km east then moves 4 km west .
So , his distance from the starting position is :
Displacement = 6 - 4 km = 2 km .
Hence , this is the required solution .
