The distance between two stations is 20 km. If a train moves with a constant speed of 60 km `h^(-1)`, then the time taken by the train to reach the next station is _____.

Options

A. 2 hour
B. 20 minute
C. 20 second
D. 40 minute

Explanation

To find the time taken by the train to reach the next station, we can use the formula:

\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

### Step-by-Step Solution:

1. **Identify the Given Values**:
- Distance between the two stations (A and B): 20 km
- Speed of the train: 60 km/h

2. **Apply the Formula**:
- Substitute the values into the formula:
\[ \text{Time} = \frac{20 \text{ km}}{60 \text{ km/h}} \]

3. **Calculate the Time**:
- Perform the division:
\[ \text{Time} = \frac{20}{60} \text{ hours} \]
- Simplifying the fraction:
\[ \text{Time} = \frac{1}{3} \text{ hours} \]

4. **Convert Hours to Minutes**:
- Since 1 hour = 60 minutes, we can convert \(\frac{1}{3}\) hours to minutes:
\[ \text{Time in minutes} = \frac{1}{3} \times 60 = 20 \text{ minutes} \]

5. **Final Answer**:
- The time taken by the train to reach the next station is **20 minutes**.
