Convert each of the following speeds in to km /hr :
14m/sec

Answer

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

### Step-by-Step Solution:

1. **Understand the conversion factors**:
- 1 kilometer (km) = 1000 meters (m)
- 1 hour (hr) = 3600 seconds (s)

2. **Set up the conversion**:
We want to convert 14 m/s into km/h. We can use the conversion factors to do this.

3. **Convert meters to kilometers**:
Since 1 meter is equal to \( \frac{1}{1000} \) kilometers, we can express 14 meters as:
\[ 14 \text{ m} = 14 \times \frac{1}{1000} \text{ km} = \frac{14}{1000} \text{ km} \]

4. **Convert seconds to hours**:
Since 1 second is equal to \( \frac{1}{3600} \) hours, we can express 1 second as:
\[ 1 \text{ s} = \frac{1}{3600} \text{ hr} \]

5. **Combine the conversions**:
Now we can combine these conversions:
\[ 14 \text{ m/s} = 14 \times \frac{1}{1000} \text{ km} \div \frac{1}{3600} \text{ hr} \]
This simplifies to:
\[ 14 \text{ m/s} = 14 \times \frac{3600}{1000} \text{ km/hr} \]

6. **Calculate the final value**:
Now, we can calculate:
\[ 14 \times \frac{3600}{1000} = 14 \times 3.6 = 50.4 \text{ km/hr} \]

### Final Answer:
The speed of 14 m/s is equivalent to **50.4 km/h**.
