two passenger trains start at the same hour in the day from two different stations and move towards each other at the rate of 16 kmph and 20 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 ?
"1 h - - - - - 4 ? - - - - - - 60 12 h rs = 16 + 20 = 36 t = 12 d = 36 * 12 = 432 answer : e"
add(multiply(divide(60, subtract(20, 16)), 16), multiply(divide(60, subtract(20, 16)), 20))
