A train 100m long passes a pole in 10s What is the speed of the train in km/hr

To find the speed of the train, we can use the formula:

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

### Step 1: Calculate the speed in meters per second (m/s)
- The train is 100 meters long.
- It takes 10 seconds to pass the pole.

\[
\text{Speed in m/s} = \frac{100 \text{ m}}{10 \text{ s}} = 10 \text{ m/s}
\]

### Step 2: Convert the speed to kilometers per hour (km/h)
To convert from meters per second (m/s) to kilometers per hour (km/h), use the conversion factor:

\[
1 \text{ m/s} = 3.6 \text{ km/h}
\]

So, the speed in km/h is:

\[
\text{Speed in km/h} = 10 \text{ m/s} \times 3.6 = 36 \text{ km/h}
\]

Thus, the speed of the train is **36 km/h**.
