ii) 360km
Step-by-step explanation:
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
