Answer:
Given that,
Speedv=60km/h
Time
t
1
=1h
t
2
=30min
Now, distance travelled by a car in East direction
D
1
=v×t
1
D
1
=60×1
D
1
=60km
Now, distance travelled by a car in south direction
D
2
=v×t
2
D
2
=60×
2
1
D
2
=30km
Now, the displacement from intial position
D=
(D
1
)
2
+(D
2
)
2
D=
(60)
2
+(30)
2
D=
3600+900
D=
4500
D=30
5
Hence, the displacement of car from initial position is 30
5
m
