Two very hungry (and competitive) pre-med students suddenly see a parked ice cream truck that is that is down to its last ice cream cone. The truck is a distance of D meters away from the nearest student, who runs toward the truck at 2.5 m/s, and the second student (who was a track star in high school) runs toward it faster at 5.7 m/s but the second student is 10.0 meters farther away (to where he has to run D+10.0 m). What is the maximum possible value of D for the two students to reach the ice cream truck at the same time?
