Congratulations to Fawntia Fowler from the Sheridan Japanese Program in Sheridan, OR. Fawntia wins the Casio CFX-9850G Color Graphing calculator.

The Track

A running track has straight parallel sides and semicircular ends. It measures Y long as you go along the inside edge of the inside lane. The innermost lane is Lane 1. The next lane to it is Lane 2. Each lane is one meter wide. Assume that the finish line is at the center of one of the straight sides and perpendicular to that straight side of the track. The race we are discussing is a one-lap race that requires runners to stay in their respective lanes for the entire race so a staggered start is necessary to compensate for the radii of the circles in the ends. How far ahead of the starting mark for Lane 1 should the starting mark for Lane 2 be placed so both runners cover the same distance as they make their lap?
