Answer:
60 min
Step-by-step explanation:
Tours for the National Capitol leave every 15 minutes
Tours for the White House leave every 20
minutes
to find Time interval at which Tour will
leave at same time, we need to find LCM
of 15 & 20
15= 3 * 5
20= 4 * 5
LCM = 3 * 4*5
= 60 mins
Every 60 Mins Tours Leave at the Same
time
