A body travels a

Answer :

1) Total distance =3+ 4 + 9 = 16 Km

2) Total displacement = 12.6 km

The net displacement in east direction is 3+9=12 km

The net displacement in north direction is 4 km

The net displacement in south and west direction is zero

Using, pythagorean theorem

displacement(d)=√(122+ 42)=√(144+16)=√(160)=12.6 km

Hence, The displacement of body is 12.6 km in north-east direction
