    5 steps of Policeman = 7 steps of a thief => 1 step of Policeman = 7/5 steps of thief => 8 Steps of Policeman = 8 x 7/5 steps of thief = 56/5 steps of thief The ratio of speeds of policeman and thief = ratio of distance covered by policeman and thief in a same time => In same time policeman moves 8 steps and thief moves 10 steps => 56/5 : 10 (because as we calculated earlier 8 steps of policeman = 56/5 steps of thief) => 56 : 50 = 28 : 25
