Mark can paint twice as fast as Joe. If Mark starts to paint at one end of a mile-long wall and Joe starts to paint at the other end of the wall, how far away from Mark's end of the wall will they meet?

A. 3/4 mile

B. 2/3 mile

C. 1/2 mile

D. 1/3 mile

E. 1/4 mile

Mark can paint twice as fast as Joe.For every 1 foot of fence that Joe paints, Mark paints 2 feet.

So, out of every 3 feet of fence that gets painted, Mark paints 2 feet

In other words, Mark does 2/3 of the work.

So, if their combined efforts yields 1 mile of painting, then we know that Mark completed 2/3 of the job.

So, Mark painted 2/3 miles of fence.
