You can put this solution on YOUR website! Antonio and Angelo are racing with remote-controlled cars around a track. Antonio's remote- controlled car finishes the track in 28 seconds, while Angelo's remote-controlled car finishes the track in 24 seconds. If they both start at the same time, after how many seconds will both Antonio and Angelo's remote-controlled cars meet each other again?
***
Angelo's car takes 4 seconds longer to complete one lap which is (1/7) of the time Antonio takes to complete one lap. After Antonio completes 8 laps, Angelo's car will have completed 7 laps, that is, Antonio will be starting his 9th lap and Angelo his 8th lap from the same starting point. This means the will meet after 8*28 or 7*32=224 seconds
