Question 156490: Karen is in the center of a circular track of radius 90 feet watching Abigail and Mercury run a race. When Abigail wins, Karen notices that the angle formed by drawing a line from the center of the track to Abigail and a line from the center of the track to Mercury measures 4 radians. How far, in feet, behind Abigail is Mercury when Abigail wins?

How far, in feet, behind Abigail is Mercury when Abigail wins?
---------------
The perimeter of the track is (pi)d = 180pi feet
----------------
Angular difference in position = 4 radians
Linear difference in position = (4/(2pi))*(180pi ft.) = 360 ft.
