Given
- First speed = 60 km/hr for 0.52 hour
- Second speed = 30 km/hr for 0.24 hour
- Third speed = 70 km/hr for 0.71 hour
Calculations
To find the average speed of the train, we need to calculate the total distance traveled by the train and the total time taken. Let's calculate these values one by one.
Total Distance
- Distance covered in the first part = 60 km/hr * 0.52 hr = 31.2 km
- Distance covered in the second part = 30 km/hr * 0.24 hr = 7.2 km
- Distance covered in the third part = 70 km/hr * 0.71 hr = 49.7 km
- Total distance traveled by the train = 31.2 km + 7.2 km + 49.7 km = 88.1 km
Total Time Taken
- Total time taken by the train = 0.52 hr + 0.24 hr + 0.71 hr = 1.47 hr
Average Speed
- Average speed of the train = Total distance / Total time taken = 88.1 km / 1.47 hr = 59.9 km/hr (approx)
Answer
The average speed of the train is approximately 59.9 km/hr.
