A polled loop system checks a binary status signal every 100s Testing the signal and vectoring to the corresponding interrupt processing routine take 15s If it takes 625s to serve the interrupt, what is the minimum response time for this polled interrupt And what is the maximum response time

Question: A polled - loop system checks a binary status signal every 100s. Testing the signal and vectoring to the corresponding interrupt processing routine take 15s.

A polled - loop system checks a binary status signal every 100μs. Testing the signal and vectoring to the corresponding interrupt processing routine take 15μs. If it takes 625μs to serve the interrupt, what is the minimum response time for this polled interrupt? And what is the maximum response time?
