Answer 1

Answer:

30√5km

Step-by-step explanation:

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
