**drwls**, Wednesday, November 14, 2007 at 8:55amLet Tb be the one-lap time for Basha.

The frequency that Basha and Dionne encounter is

1/48 = 1/120 + 1/Tb, so

1/Tb = 10/480 - 4/480 = 6/480 = 1/80

Tb = 80 seconds

With Sandra and Basha running in opposite directions, and Basha running so fast, they would have to meet more often than every 240 seonds. I believe you made and error stating that Sandra runs clockwise, opposeite to Basha. Check the wording of the problem again.
