Answer:
2 Times
Step-by-step explanation:
Simon can see two lights A and B
- 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 15 and 18.
15=3X5
18=
LCM of 15 and 18=
This means that lights A and B will first flash together after 90 seconds.
Now, 240/90= seconds
Therefore, the number of times more both light will flash together in the next 4 Minutes= 2 Times
