The average speed of a train running at a speed of 30 km/h during the first 100 km, at the speed of 40 km/h during the second
100 km and at the speed of 50 km/h during the last 100 km is nearly ________.
40.2 km/h
38.3 km/h
39.2 km/h
37.5 km/h
To find the average speed of the train:
- Calculate the total distance:
- 1st segment: 100 km
- 2nd segment: 100 km
- 3rd segment: 100 km
- Total distance = 300 km
- Calculate the time for each segment:
- 1st segment: 100 km / 30 km/h = 3.33 hours
- 2nd segment: 100 km / 40 km/h = 2.5 hours
- 3rd segment: 100 km / 50 km/h = 2 hours
- Total time = 3.33 + 2.5 + 2 = 7.83 hours
- Calculate the average speed:
- Average speed = Total distance / Total time
- = 300 km / 7.83 hours
- ˜ 38.3 km/h
?? Hence, the correct choice is: Option 2: 38.3 km/h
