Two television stations are running the same advertisement. One television stations runs the advertisement eveey 24 minutes and the other television station runs the advertisement every 18 minutes. Both stations have the advertisement on right now. How many minutes until both stations will have the advertisement on again at the same time?

72 minutes

Step-by-step explanation:

Given that:

Advert runs on :

Station 1 : every 24 minutes

Station 2 : every 18 minutes

Both have the advert running presently ; How many minutes until both stations will have the advertisement on again at the same time?

To obtain the time the advert will run again at the same time on both stations, we find the Lowest common factor of 24 and 18

_2__24 18

_2__129

_2__6 9

_3__3 9

_3__1 3

11

2 * 2 * 2 * 3 * 3 = 72

After 72 minutes

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
