Single Chоice. The pоrtiоn of time а progrаm spends performing floаting-point operations is 20%. A new floating-point coprocessor would perform floating-point operations four times as fast. Given that the execution time of a program required 40 seconds without the new floating-point coprocessor, what would you expect the execution time of the program to be in seconds with the new floating-point coprocessor?
