A bird flies 6km east, then 4km west. Find the total distance traveled and displacement (d) after this flight.

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 .

i think it would be 80 km/h because 30 + 50 = 80 (sorry if this not the right answer i'm trying my best)

e) none of the above answers are correct
