4. What was her average velocity?​

Answer 1

Answer:

2.What was her displacement?:3

Explanation:

2.What was her displacement :3

Answer 2

Answer:

1. The distance she covered is $12 km ( 1200 m )$
2. The Displacement is $2 km North$
3. The average speed is $9.09 m/s$
4. The average velocity is​$9.09 m/s North$

Explanation:

1. Distance is the total km covered by someone $7+5= 12km$

2. Displacement is the shortest route between the starting point and finishing point. She drove $7km$ north and $5km$ south thus $7-5= 2km$

3. $Speed = \frac{distance}{time}$

$speed= \frac{12000}{1320}$

$speed= 9.09 m/s$

4.  $Speed = \frac{distance}{time}$

$speed= \frac{12000}{1320}$

$speed= 9.09 m/s$
