Answer» Given :- ALLEN and annie travel at x m /s and y m /s respectively. if the distance covered by both of them is the same , what is the ratio of the time TAKEN by allen to that of annie ? Solution :- LET us assume that, distance covered by them is D m . so, → Allen speed = x m/s → Distance = D m → Time = D/S = D/x m/s and, → Annie speed = y m/s → Distance = D m → Time = D/S = D/y m/s then, → Time ratio = D/x : D/y = Dy : Dx /xy = y : x (Ans.) therefore, we can conclude that,
