Answer:
they will meet in 30 days
Step-by-step explanation:
circumference = 360 km
d by 1st cyclist = 48 km
n (no. of days to cover the round) = 360/48 = 7.5 days = 7.5 * 24 = 180 hours
d by 2nd cyclist = 60 km
n = 360/60 = 6 days = 144 h
d by 3rd cyclist = 72 km
n = 360/72 =5 days = 120 h
TO FIND = LCM OF 180, 144, 120 = 720 hours
720/24 = 30 days
