Let Vitoria and Margaret met after x hrs.
Time taken by both = x hr.
Speed of Vitoria = 55 mph.
Speed of Margaret = 70 mph.
Distance = Speed * Time
Distance covered by Victoria in x hrs = 55x miles
Distance covered by Margaret in x hrs = 70x miles.
Total Distance = 70x + 55x
625 = 70x+55x [Since, Distance between Victoria and Margaret is 625 miles]
625 = 125x
Victoria and Margaret met after 5 hrs. Ans.
