A typist is entering text on a keyboard at the rate of $30$ words per minute. If each word is $6$ characters long on average, what bandwidth in bits per second between the keyboard and main memory is required to transmit the information? A space is also a character. Assume that each word is followed by one space on average. Provide only the number to the nearest whole bits$/$sec$.$

Example $42$ not $42\mathrm{.}34\frac{b}{s}$
