Estimate the transaction states, Database Management System

Suppose an instruction takes 1 nanosecond to execute (on average), a page fault takes 20 microseconds of processor time, and it takes 300 microseconds of disk time to read or write a single page. Suppose that on average, 1/2 of the pages are modified. What is the average number of instructions between page faults that would cause the disk to be busy doing page transfers all the time?
