Odell and Kershaw run for 30 minutes on a circular track. Odell runs clockwise at 250 m/min and uses the inner lane with a radius of 50 meters. Kershaw runs counterclockwise at 300 m/min and uses the outer lane with a radius of 60 meters, starting on the same radial line as Odell. How many times after the start do they pass each other?
I NEED YOU CPHILL OR ELECTRICPAVLOV OR ANYBODY ELSE!!!!!!!
How may laps does Odell run? 250m/min * 30 min / (pi *d) = 250*30 / (pi *100) = 23.87 laps
Kershaw runs 300m/min *30 min /(pi *d) = 300*30/(pi*120) = 23.87 laps in the same time
The pass each other TWICE each lap and only ONCE for the .87 lap = 47 times (?) Not positive....
