Solution:
Given that,
It takes Alyssa's car 15 seconds to go one complete run around the track
It takes Luke's car 12 seconds to go around the track one time
How many seconds will it take for both cars to return to the starting point at the same time?
So, we need to find the LCM of 15 and 12
LCM of 15 and 12
Prime factors of 15 = 3 x 5
Prime factors of 12 = 2 x 2 x 3
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 2, 3, 5
Multiply these factors together to find the LCM.
LCM = 2 x 2 x 3 x 5 = 60
Thus, it takes 60 seconds for both cars to return to the starting point at the same time
