Tram stop

The blue tram stops every 12 minutes, the red one for 8 minutes. At 8 o'clock, they left the stop together. How many times do they meet at a stop before 11 AM?

Correct answer:

n =  7

Step-by-step explanation:

t=(118) 60=180 min 12=223 8=23 LCM(12,8)=233=24  s=LCM(12,8)=24 min  n1=t/s=180/24=215=721=7.5  n=n1=7.5=7
