Two hours later, John leaves, driving at the rate of 48 mi/h. At what time will John catch up with Martina?Answer by wuwei96815(245)   (Show Source): You can put this solution on YOUR website!This problem involves the equation distance = speed x time, or at least part of the equation. The question is really asking at what point will the distance that Martina travels be equal to the distance that John travels? Martina's distance = 24 mph x (t + 2) because she starts off two hours before John. John's distance = 48mph x t 24mph x (t+2) = 48mph x t 24t + 48 = 48t 48 = 48t-24t 48 = 24t 2 = t They will meet 2 hours after John starts. That will be at 1 P.M. Did you understand the solution?
