Aman, Anna, and Tina are participating in the school race. Anna completes a lap in 120 minutes, Aman completes a lap in 240 minutes, and Tina completes a lap in 60 minutes. If they all started at the same time, then after how long will they meet again?

Correct answer:

t =  240 min

Step-by-step explanation:

120=2335 240=2435 60=2235 LCM(120,240,60)=2435=240  t=LCM(120,240,60)=240 min
