so we'll write two equations. 1st 40 over Axe equals 15 over alive. And then our second equation is that actually goes wide. Last one. So the way we got this first equation is we know that Dean was Artie and the teaser equal for Paul and Carlos. So we can say I d over our people's d over our for each separate person where axe is gonna be the speed of Carlos and wise this beautiful this we got from our second piece of information. So now we will substitute in our X value. So we get 15. Why lost 300 people's why her equals 40 wine. So from this, we can determine that y equals 12. And on the other line was 12 when you just plummeted right here to find out. So we know that X equals 32. So these are solutions. Um, Paul and Carlos is speeds
