$1\mathrm{.}15$ Assume a program requires the execution of $50{10}^{6}FP$ instructions, $110{10}^6$ INT instructions, $80{10}^6\frac{L}{S}$ instructions, and $16{10}^6$ branch instructions. The CPI for each type of instruction is $1,1,4,$ and $2,$ respectively. Assume that the processor has a $2GHz$ clock rate.
