To the best of my understanding the triplets in this case each take on the value of one beat (one-and)and the three notes equally share the time spread of that count. As I have been taught, the count of the measure would sound like this. One-and-uh Two-and-uh three four. The four portions of the measure would take up equal amounts of time meaning that each note of the triplet would play more quickly than if there were two eighth notes.
