In a corporate environment utilizing VMware Workspace ONE Intelligence, a company is analyzing user engagement metrics across various applications. The IT team has noticed that the average session duration for a specific application is significantly lower than the company’s benchmark of 30 minutes. They decide to implement a series of targeted notifications to encourage users to engage more with the application. After implementing these notifications, they observe a 25% increase in average session duration over the next month. If the average session duration before the notifications was 20 minutes, what is the new average session duration after the increase?
