The bus that travels from St. Louis to Chicago and back comes to St. Louis every 4 hours while the bus that travels from St. Louis to Springfield and back comes to St. Louis every 6 hours. If at 12:00 o'clock both bused arrived at St. Louis, at what time will they meet in St. Louis again?
A. 16:00.
B. 18:00.
C. 20:00.
D. 22:00.
E. 24:00.
The OA is E.
Bus one frequency is 6 hours
Bus two frequency is 4 hours
they will meet again after LCM(6,4)=12 hours
now, both buses arrived at 12 the next time they will meet is at 12+12 = 24:00
Please, can anyone explain another way to solve this PS question? Thanks!
