selina can run around the track 3 times in 8 minutes. marta can run around the same track 2 times in 5 minutes. if selina and marta begin at the same time and the same place what is the combined number of laps the girls both will have run when they next reach the starting point at the same time?

all you need to know is the lcm of 8 and 5.... because it doesnt specify how many times they had to complete the track...
