A train travels 90 kilometers/hr. How many hours does it take the train to travel 450,000 meters? (1 kilometer = 1,000 meters)

Answer

To solve the problem of how many hours it takes for a train traveling at 90 kilometers per hour to cover 450,000 meters, we can follow these steps:

### Step-by-Step Solution:

1. **Convert meters to kilometers**:
We know that 1 kilometer is equal to 1,000 meters. Therefore, to convert 450,000 meters to kilometers, we divide by 1,000.
\[ \text{Distance in kilometers} = \frac{450,000 \text{ meters}}{1,000} = 450 \text{ kilometers} \]

2. **Use the formula for time**:
The formula to calculate time when distance and speed are known is:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

3. **Substitute the values into the formula**:
We have the distance as 450 kilometers and the speed as 90 kilometers per hour. Now we can substitute these values into the formula:
\[ \text{Time} = \frac{450 \text{ kilometers}}{90 \text{ kilometers per hour}} \]

4. **Calculate the time**:
Performing the division:
\[ \text{Time} = \frac{450}{90} = 5 \text{ hours} \]

### Final Answer:
The train takes **5 hours** to travel 450,000 meters.
