. Zara travelled in a train moving at an average speed of 120km/h and covered a distance of 40km towards East. ⦁ She further travelled for 3hours at a speed of 120km/h towards North. Calculate the distance she covered in this time.

The question is incomplete. Here is the complete question.

Q2. Zara travelled in a train moving at an average speed of 120km/h and covered a distance of 40km towards East.

i. Calculate the time taken by the train to cover this distance.

ii. She further travelled for 3hours at a speed of 120km/h towards North. Calculate the distance she covered in this time.

1) Using the formula for calculating speed

Speed = Distance/Time

If Zara traveled at an average speed of 120km/h and covered a distance of 40km towards East,

Distance covered = 40km

Speed = 120km/hr

Time taken = Distance/Speed

Time taken = 40/120

Time taken = 1/3 hr

Time taken = 1/3 * 60 = 20 minutes

ii) If she further travelled for 3hours at a speed of 120km/h towards North,

Her speed = 120km/hr

Time Taken = 3hours

Distance covered this time = Speed *Time

Distance covered this time = 120 * 3

Distance covered this time = 360km

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

think its the third option
