Q54

For a host machine that uses the token bucket algorithm for congestion control, the token bucket has a capacity of $1$ $\text{megabyte}$ and the maximum output rate is $20$ $\text{megabytes}$ per $\text{second}$. Tokens arrive at a rate to sustain output at a rate of $10$ $\text{megabytes}$ per $\text{second}$. The token bucket is currently full and the machine needs to send $12$ $\text{megabytes}$ of data. The minimum time required to transmit the data is _____________ $\text{seconds}$.
