Rishabh of Raxaul skated the 10,000m race
in Salt Lake City in 12 min. 58.92 seconds.
The oval track is made up of two straight
112.00m sections and two essentially
identical semicircular curves. There are
two lanes, each 5.00m wide. The 400m lap
starts at A on the inner straightway, rounds
the inner curve, crosses over in the next
straight section in the shortest diagonal
path to the outside lane (the other skater
crosses over the other way), and rounds the
outer curve, ending up on the adjacent lane
at B (see dotted line). The measurement is
made 5cm out form the inner edge of the
lane, and is exactly 400m for one lap. What
is the radius of the inner curve, R in m?
