A motor car covers 1/3 part of total distance with velocity v1=10km/hr...
Given information:
- A motor car covers 1/3 part of total distance with velocity v1=10km/hr.
- Second 1/3 part with velocity v2=20km/hr.
- Rest 1/3 part with velocity v3=60km/hr.
To find:
- The average speed of the car.
Solution:
Let's assume that the total distance covered by the car is d km.
- Distance covered in the first 1/3 part of the journey = d/3.
- Distance covered in the second 1/3 part of the journey = d/3.
- Distance covered in the rest 1/3 part of the journey = d/3.
Now, we can calculate the time taken to cover each distance using the formula:
Time = Distance / Velocity
- Time taken to cover the first 1/3 part of the journey = (d/3) / 10 = d/30 hours.
- Time taken to cover the second 1/3 part of the journey = (d/3) / 20 = d/60 hours.
- Time taken to cover the rest 1/3 part of the journey = (d/3) / 60 = d/180 hours.
Total time taken to cover the entire distance = (d/30) + (d/60) + (d/180) = (2d/45) hours.
Now, we can calculate the average speed of the car using the formula:
Average Speed = Total Distance / Total Time
- Total Distance = d km.
- Total Time = (2d/45) hours.
Average Speed = d / (2d/45) = 22.5 km/hr.
Therefore, the average speed of the car is 22.5 km/hr.
Answer: a) 196m.
- A motor car covers 1/3 part of total distance with velocity v1=10km/hr.
- Second 1/3 part with velocity v2=20km/hr.
- Rest 1/3 part with velocity v3=60km/hr.
To find:
- The average speed of the car.
Solution:
Let's assume that the total distance covered by the car is d km.
- Distance covered in the first 1/3 part of the journey = d/3.
- Distance covered in the second 1/3 part of the journey = d/3.
- Distance covered in the rest 1/3 part of the journey = d/3.
Now, we can calculate the time taken to cover each distance using the formula:
Time = Distance / Velocity
- Time taken to cover the first 1/3 part of the journey = (d/3) / 10 = d/30 hours.
- Time taken to cover the second 1/3 part of the journey = (d/3) / 20 = d/60 hours.
- Time taken to cover the rest 1/3 part of the journey = (d/3) / 60 = d/180 hours.
Total time taken to cover the entire distance = (d/30) + (d/60) + (d/180) = (2d/45) hours.
Now, we can calculate the average speed of the car using the formula:
Average Speed = Total Distance / Total Time
- Total Distance = d km.
- Total Time = (2d/45) hours.
Average Speed = d / (2d/45) = 22.5 km/hr.
Therefore, the average speed of the car is 22.5 km/hr.
Answer: a) 196m.
