Given a computer running four types of instuctions, named classes A through D, calculate the execution time of a program that has an instruction count per category as follows: Class A: 8 millions of instructions, with an average CPI of 4.1, Class B: IC of 6M and CPI of 4.1, Class C: IC of 9M and CPI of 1.1, and Class D: IC of 2M and CPI of 1. The CPU runs at 6MHz. What is the compute time of this program in seconds? Round to 2 decimal places.
