You create a service level agreement (SLA) for cases where the case priority is critical. The SLA must display a warning after 15 minutes and fail after 30 minutes. You create a normal priority case at 16:00. You change the priority to critical at 16:15. If no action is taken, how many minutes will elapse before the SLA fails?
