Answer:
Given:
- A body covers 1/3rd part of total distance with 10km/h
- The second 1/3rd part with 20km/h
- The third 1/3rd part with 60km/h
To Find: Average speed of the body
Solution:
Let's assume the total distance as D.
Then, the distance covered in each part will be:
- 1st part = D/3
- 2nd part = D/3
- 3rd part = D/3
Let's calculate the time taken to cover each part:
- 1st part = (D/3) / 10 = D/30 hours
- 2nd part = (D/3) / 20 = D/60 hours
- 3rd part = (D/3) / 60 = D/180 hours
Now, let's calculate the total time taken:
Total Time = (D/30) + (D/60) + (D/180) = (2D/45) hours
Finally, let's calculate the average speed:
Average Speed = Total Distance / Total Time
Average Speed = D / (2D/45) = 22.5 km/h
Therefore, the average speed of the body is 22.5 km/h.
