Question 847560: Mary and Linda live 324 miles apart. They start at the same time and travel toward each other. Mary's speed is 8 mph greater than Linda's If they meet in 3 hours find their speeds.
I have tried 3h-8=324 that did not work
I tried 3x-8y=324 that did not work
and i tried 3(x-y)=324-8 and that did not work.
I take classes online so it's really hard to learn this just by the book.
