## 153. Math Puzzle $2 / 78$

The computer KRS 4200, manufactured by VEB Robotron, has a cycle time of $1.3 \mu \mathrm{s}$, i.e., it requires $1.3 \mu \mathrm{s}$ for one computational operation.

What frequency does this correspond to, and how many tasks can it solve on average in 1 minute?

Hint: Frequency indicates the number of regularly recurring events per second.
The frequency $f$ indicates the number of processes $n$ in a certain time $t$ and is calculated using the formula $f=\frac{n}{t}$.

For $n=1$, $f=\frac{1}{T}$, where $T$ represents the duration of one process, for example, the cycle time of the computer.

$$
f=\frac{1}{T}=\frac{1}{1.3 \cdot 10^{-6} \mathrm{~s}}=770 \cdot 10^{3} \frac{1}{\mathrm{~s}}
$$

The frequency of the computer is therefore $770 \mathrm{kHz}$, and it can solve approximately 46.2 million tasks in one minute.
