I need help understanding and doing the question below regarding Amdahl's law

I need help understanding and doing the question below regarding Amdahl's law (which deals with benchmarks and CPU performance/execution time).

 

The question is:

 

We are testing some benchmark tasks to show off performance of floatingpoint

units (comparing old and new floating-point hardware). One benchmark we are

considering runs for 100 seconds (total initial execution time) with the old floating-point

hardware. We observed the overall benchmark showing a speedup of 3 due to the

floating-point enhancement with a new floating-point unit running 5 times faster. How

much of the initial execution time would floating-point instructions have to account for?
