Pleas solving the problems step by Stebe to understand .....?

With a 20 MHz clock (Fosc), how long does it take to execute 13 instruction cycles? Give the answer in microseconds. For reference, 1 MHz has a period-1 us 1000 ns. Show ALL your calculations to receive full credit. 1 ?5-10 s, l ns-109 s, 1 MHz-106 Hz. l. C) 15. Time: 1.3 us. Give 16. Show your work: {26 clock cycles)lsec/20*10E6 cycles)-1.3us s just a number: 3.14 not 3.14 us
