Question

A rabbit lure on a greyhound racetrack is set to travel once around the track at 50 feet per second, and then its speed is increased to 65 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 184 seconds, what is the distance once around the track?

Answer 1

184 sec = Circumference / 50 fps + Circumference / 65 fps
184 = 65 Circumference/3250 + 50 Circumference/3250
184 = 115 Circumflex/3250
598000 = 115 Circumflex
Circumflex = 5200 ft
the answer would be 5200ft
