------------
Leroy DATA:
Rate = 50 km/hr ; Time = x hrs. ; Distance = rt = 50x km
---------------
Tina DATA:
Rate = 75 km/hr ; Time = (x-1) hrs. ; Distance = 75(x-1) = 75x-75 km
-----------------
EQUATION:
distance = distance
50x = 75x-75
-25x=-75
x=3 hrs (Leroy's time)
x-1 = 2 hrs (Tina's time)
=========================
