Ann and Bea are at opposite sides of a CIRCULAR track. At 12:00 pm, Ann starts traveling clockwise at a constant speed of 25 kilometers per hour. At the same time, Bea starts traveling counter-clockwise at a constant speed of 10 kilometers per hour. At 1:30 pm that same day, Ann and Bea cross paths for the SECOND time. What is the circumference (in kilometers) of the circular track?
A) 17.5
B) 35
C) 42
D) 52.5
E) 70
* Kudos for all correct solutions[/quote]
i have a different approach assume Bea is not moving so ANN speed will be 25+10 = 35
distance travelled in 1.30 hour = 35* 1.5 = 52.5 kms
so Ann meet Bea first time in half circle and second time full circle round so
1.5x = 52.5 kms
x = 35 kms
