To determine how far the train will have traveled from its starting point after a total of 9 hours, we first need to calculate its average speed.
1. **Calculate the average speed**:
- Distance = 250 km
- Time = 5 h
- Average Speed = Distance / Time = 250 km / 5 h = 50 km/h
2. **Calculate the distance traveled in the next 4 hours**:
- Time = 4 h
- Distance = Speed × Time = 50 km/h × 4 h = 200 km
3. **Total distance traveled from the starting point after 9 hours**:
- Initial distance = 250 km
- Distance in the next 4 hours = 200 km
- Total Distance = 250 km + 200 km = 450 km
Therefore, if the train continues at the same average speed for another 4 hours, it will have traveled a total of **450 km** from its starting point.
The correct answer is:
C) 450 km
1. **Calculate the average speed**:
- Distance = 250 km
- Time = 5 h
- Average Speed = Distance / Time = 250 km / 5 h = 50 km/h
2. **Calculate the distance traveled in the next 4 hours**:
- Time = 4 h
- Distance = Speed × Time = 50 km/h × 4 h = 200 km
3. **Total distance traveled from the starting point after 9 hours**:
- Initial distance = 250 km
- Distance in the next 4 hours = 200 km
- Total Distance = 250 km + 200 km = 450 km
Therefore, if the train continues at the same average speed for another 4 hours, it will have traveled a total of **450 km** from its starting point.
The correct answer is:
C) 450 km
