Snow Splash (Posted on 2005-05-15) Difficulty: 2 of 5
A field in the shape of a right triangle (with the two shortest sides measuring 60 feet and 80 feet) has roads on all three sides that don't drain properly. As a result, muddy water puddles collect and when the cars pass through, they splash all the snow that is within 5 feet of any one of the three roads.

If all other snow not splashed by cars is kept clean, what percent is clean?

different answer, four years on | Comment 6 of 8 |

Okay, so I just did the whole thing by hand, expecting to get the same answer as everyone else, but...I didn't.  The last couple of times this has happened, I've just been so wrong, so this could be like that.  But working this all out, I got approximately 66%.  66.015625%. 

By the way, the quadrilaterals in the corners are referred to as kites in most of the comments, but they're not.  They're parallelograms.  I wonder if that's what the issue is?  I found the sides of the smaller triangle to be 48.75 and 65.
