Stop

Three tram lines pass through the stop on Malé náměstí. Tram number 9 arrives regularly at 8-minute intervals, tram number 12 stops every 10 minutes, and tram number 13 stops every 12 minutes. How many times will all three tram lines stop at the stop simultaneously before 4 p.m.?

Final Answer:

n =  8

Step-by-step explanation:

8=23 10=25 12=223 LCM(8,10,12)=2335=120  a=LCM(8,10,12)=120 min t=16 h min=16 60  min=960 min  n=t/a=960/120=8
