$1800$ seconds.

#### Explanation:

There are $30$ minutes in half of an hour, and $60$ seconds in a minute.

There are $60$ seconds for every minute, and we have $30$ minutes, so we multiply $30$ and $60$.

$30 \cdot 60 = 1800$ seconds.

$\frac{1}{2} \times 60 \times 60 = 1 , 800$ seconds.

#### Explanation:

It is possible that the fraction makes this question look a bit difficult. However, it follows the same method as any other conversion from hours to seconds.

There are $60$ minutes in $1$ hour and $60$ seconds in $1$ minute.

So convert a number of hours to seconds, multiply by $60 \times 60$

$1 \text{ hours} = 1 \times 60 \times 60 = 3 , 600$ seconds
$3 \text{ hours} = 3 \times 60 \times 60 = 10 , 800$ seconds

If you have a fraction of n hour, the same method applies.

$\frac{1}{2} \times 60 \times 60 = 1 , 800$ seconds.
