cache cpu – Architecture – calculation of the penalty for absence

I know it Access Time to AVG Memory = Response Time + Loss Rates * Loss Penalty

If you give me the AMAT and the miss rate, as well as the memory access time (call this x), how can I calculate the miss penalty and / or the typing time?

For example:

AMAT = 80 (cycles)
Miss Rate = 0.4
Latency of access to the memory = 60 (cycles)

How can I get a missing penalty in order to be able to resolve my delay?

Thank you
