To calculate the average speed of the train, you can use the formula:
\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]
Here, the total distance is 210 km and the total time is 1.5 hours.
Using the formula:
\[
\text{Average Speed} = \frac{210 \text{ km}}{1.5 \text{ h}} = 140 \text{ km/h}
\]
So, the average speed of the train is 140 km/h.
The correct answer is:
**140 km/h**
\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]
Here, the total distance is 210 km and the total time is 1.5 hours.
Using the formula:
\[
\text{Average Speed} = \frac{210 \text{ km}}{1.5 \text{ h}} = 140 \text{ km/h}
\]
So, the average speed of the train is 140 km/h.
The correct answer is:
**140 km/h**
