2 men plan to meet at the town's clock tower on 29 Aug 2009 between 4pm to 6 pm. But they are both very impatient and cant wait more than 20 mins for the other person to come. so they can come anytime between 4 to 6 and will go after 20 minutes if the other person doesn't come this while. What is the probability that their meeting will be successful?

Plot
|x-y|<20
in the square of side 120
The area ratio will give the probability.
