Question 973381: It takes Michael 60 seconds to run around a 440-yard track. How long does it take Jordan to run around the track if they meet in 32 second after they start together in a race around the track in opposite direction? Answer by macston(5194) (Show Source):

Michael runs at a rate of 440yds/60s=7.33yds/s.
In 32 seconds he runs (32s)(7.33yd/s)=234.67yds.
When they meet, Jordan has run 440yds-234.67yds=205.33yds
So Jordan runs at a rate of 205.33yds/32sec=6.42yds/s
To run the whole track (440 yardsds), it takes Jordan:
440yds/6.42yds/s=68.54s
.
ANSWER: It takes Jordan 68.54 seconds to run around the track.
