Answer:
2 Times
Step-by-step explanation:
Light A flashes every 15 seconds.
Light B flashes every 18 seconds.
First, we determine the next time both lights will flash together.
This is done by finding the Least Common Multiple of the two numbers.
15=3X5
18=
LCM of 15 and 18=
This means that both lights will flash together after 90 seconds.
Now, 4 Minutes =4 X 60 =240
240=90+90+60
Therefore, the number of times more both light will flash together in the next 4 Minutes
= 2 Times
