a and b go around a circular track of length 300 m on a cycle at speeds of 34 kmph and 50 kmph . after how much time will they meet for the first time at the starting point ?
"time taken to meet for the first time at the starting point = lcm { length of the track / speed of a , length of the track / speed of b } = lcm { 300 / ( 36 * 5 / 18 ) , 300 / ( 54 * 5 / 18 ) } = lcm ( 30 , 20 ) = 60 sec . answer : b"
divide(300, subtract(multiply(50, const_0_2778), multiply(34, const_0_2778)))
