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.
