1) What would be the execution time for a program containing 2.,000,000 instructions if the processor clock were running at 8 MHz and each instruction took four clock cycles?

2) Asman architect reimplements a given instruction-set architecture, halving the CPI for 50% of the instructions while increasing the clock cycle time of the processor by 10%. How much faster is the new implementation, compared with the original? Assume that all instructions are equally likely to be used in determining the execution time of any program.

please help me both questions. thank you
