So let's take a holistic approach: the most time we can count using ONE of the hourglasses is 8 minutes: by starting the 4-minute hourglass, flipping it, then letting it go for another 4-minutes. Let's say we start both the 4-minute and the 7-minute hourglass at the same time. The 7-minute hourglass runs out before 8-minutes are up, so we flip it.
