[ARCHIVED THREAD] - I need help with a math problem.

Jim paddles from one shore of a lake three miles wide at 4 mph, and John paddles from the opposite shore at 5 mph. How long will they travel before they meet?

20 minutes

Jim travels at 4x. John travels at 5x. Combined, they travel towards themselves at 9x. Lake is three miles wide so x being the time means they meet at 1/3 hour or 20 minutes.

Distance traveled is 1/3*rate, for Jim that is 4/3 mile. John travels 5/3 mile. Together, they travel 9/3 miles, or 3 miles.

Time=(Distance/Rate)=[3/(4+5)]=(1/3)hr=20 minutes.

Jeff set out to paddle across the lake as well... but he lost all his guns when the boat tragically sank.

I thought it was 20 minutes, but I just wanted to make sure.

50min.

You didn't calculate in the beer run to Sneaky Pete's

Then what did they do? Underwater bumpfire? Brokeback scuba? I hate it when people don't finish a story.

You guys are slipping--no one asked why they wanted to meet in the middle of a lake.

Edit: Well, crap--Home_With_Kids beat me while I was typing.

Have I mentioned lately you got a purty mouth?
