Problem: two passenger trains start at the same hour in the day from two different stations and move towards each other at the rate of 25 kmph and 21 kmph respectively . when they meet , it is found that one train has traveled 60 km more than the other one . the distance between the two stations is ?
Rationale: "1 h - - - - - 5 ? - - - - - - 60 12 h rs = 25 + 21 = 46 t = 12 d = 46 * 12 = 552 answer : c"
annotated_formula: add(multiply(divide(60, subtract(21, 25)), 25), multiply(divide(60, subtract(21, 25)), 21))
