Tours for the White House leave every 20 minutes. How often do the tours leave at the same time?
1 answer:
Answer:
60 minutes
Step-by-step explanation:
To solve for the above question, we use the Lowest Common Multiple Method
We are told in the question that:
Tours for the National Capitol leave every 15 minutes. Tours for the White House leave every 20 minutes.
Find and list multiples of each number of minutes until the first common multiple is found. This is the lowest common multiple.
Multiples of 15:
15, 30, 45, 60, 75, 90
Multiples of 20:
20, 40, 60, 80, 100
Therefore,
LCM(15, 20) = 60
Therefore, the tours leave at the same time every 60 minutos
