A rabbit lure on a greyhound racetrack is set to travel once around the track at 40 feet per second, and then its speed is increased to 50 feet per second for the second loop around the track. If the total time it takes for the lure to go around the track twice is 135 seconds, what is the distance once around the track?
---------------
Avg speed = 2*40*50/(40+50) = 400/9 ft/sec
d = r*t = (400/9)*135 = 6000 ft
