Answer» Answer: Let us consider Time is taken = t Speed = x Distance = d Time = Distance/Speed or Speed = Distance/time x = d/t d = xt………………………………….(1) Case 1: d = (x + 10)(t – 2) d = xt – 2x +10t -20 d = d – 2x +10t -20 [from (1) xt = d] 10t – 2x = 20…………………………………..(2) Case2: d = (x – 10)(t + 3) d = xt + 3X -10t – 30 d = d + 3x -10t – 30 [from (1) xt = d] 3x -10t = 30…………………………………..(3) Adding equation (2) and (3) (10t – 2x + 3x -10t) = 20 + 30 x = 50 Substituting the VALUE of x in 2 10t – 2 × 50 = 20 10t = 100 + 20 10t = 120 t = 12 hours Now substitute the value of t and in x in equation (1) Distance d = xt d = 50 × 12 d = 600 km Therefore distance covered by the train is 600km.
