Convert the following speed in km/hr
60 m/sec

Answer

To convert a speed of 60 meters per second (m/s) into kilometers per hour (km/hr), we can follow these steps:

### Step-by-Step Solution:

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

2. **Set up the conversion**:
- We want to convert 60 m/s to km/hr. We can express this as:
\[ 60 \, \text{m/s} = 60 \, \text{m} \times \left(\frac{1 \, \text{km}}{1000 \, \text{m}}\right) \times \left(\frac{3600 \, \text{s}}{1 \, \text{hr}}\right) \]

3. **Perform the calculations**:
- First, convert meters to kilometers:
\[ 60 \, \text{m} \times \frac{1 \, \text{km}}{1000 \, \text{m}} = \frac{60}{1000} \, \text{km} = 0.06 \, \text{km} \]
- Next, convert seconds to hours:
\[ 0.06 \, \text{km/s} \times 3600 \, \text{s/hr} = 0.06 \times 3600 \, \text{km/hr} \]
- Now calculate \(0.06 \times 3600\):
\[ 0.06 \times 3600 = 216 \, \text{km/hr} \]

4. **Final result**:
- Therefore, the speed of 60 m/s is equal to **216 km/hr**.
