To find the time it takes for the train to travel a distance of 605 kilometers at a speed of 55 km/h, you can use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
Substituting the given values into the formula:
\[ \text{Time} = \frac{605 \text{ km}}{55 \text{ km/h}} \]
Calculating this gives:
\[ \text{Time} = 11 \text{ hours} \]
So, it will take the train 11 hours to travel a distance of 605 kilometers at a speed of 55 km/h.
