Speed of the train is 60 km/h, then find the speed of m/s.

Options

A. 16.67 m/s
B. 18.25 m/s
C. 17 m/s
D. none of these

Answer

To convert the speed of the train from kilometers per hour (km/h) to meters per second (m/s), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the given speed**:
- The speed of the train is given as 60 km/h.

2. **Convert kilometers to meters**:
- We know that 1 kilometer (km) is equal to 1000 meters (m).
- Therefore, to convert 60 km to meters:
\[ 60 \text{ km} = 60 \times 1000 \text{ m} = 60000 \text{ m} \]

3. **Convert hours to seconds**:
- We know that 1 hour (h) is equal to 3600 seconds (s).
- Therefore, to convert 1 hour to seconds:
\[ 1 \text{ h} = 3600 \text{ s} \]

4. **Calculate the speed in m/s**:
- Now, we can convert the speed from km/h to m/s using the formula:
\[ \text{Speed in m/s} = \frac{\text{Speed in km/h} \times 1000}{3600} \]
- Substituting the values:
\[ \text{Speed in m/s} = \frac{60 \times 1000}{3600} = \frac{60000}{3600} \]

5. **Simplify the fraction**:
- To simplify \( \frac{60000}{3600} \):
\[ \frac{60000 \div 600}{3600 \div 600} = \frac{100}{6} \approx 16.67 \]

6. **Final answer**:
- Therefore, the speed of the train in meters per second is approximately **16.67 m/s**.
