A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?

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

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

Here:
- The speed of the train is given as \(60 \, \text{km/hr}\).
- The time taken to cross the pole is \(9\) seconds.

First, we need to convert the speed from kilometers per hour to meters per second.

\[
\text{Speed in m/s} = \frac{60 \, \text{km/hr} \times 1000 \, \text{m/km}}{3600 \, \text{s/hr}} = \frac{60000 \, \text{m}}{3600 \, \text{s}} = 16.67 \, \text{m/s}
\]

Now, we can calculate the length of the train:

\[
\text{Length of the train} = \text{Speed} \times \text{Time} = 16.67 \, \text{m/s} \times 9 \, \text{s} = 150 \, \text{meters}
\]

So, the length of the train is \(150\) meters.
