Brenda and Sally run in opposite direction on a circular track, starting at diametrically opposite points. They first meet after Brenda has run 50 meters. They next meet after Sally has run 150 meters past their first meeting point. Each girl runs at a constant speed. What is the length of the track in meters? Choose the most appropriate option:
A) 250  B) 300  C) 350  D) 400  E) 500
Nice problem. +1.   First timetogetherthey run half of the circumference.   Second timetogetherthey run full circumference.   First time Brenda runs 50 meters, thus second time she runs 2*50=

<output>100</output>
100 meters.   Since second time (when they run full circumference) Brenda runs 200 meters and Sally runs 150 meters, thus the circumference is 100 + 150= 
<gadget id="calculator">100 + 150</gadget>
<output>250</output>
250 meters.   250nswer: 250.
