On her annual road trip to visit her family in Seal Beach, California, Traci stopped to rest after she traveled 1⁄3 of the total distance and again after she traveled 1⁄4 of the distance remaining between her first stop and her destination. She then drove the remaining 300 miles and arrived safely at her destination. What was the total distance, in miles, from Traci’s starting point to Seal Beach?  Choose the correct option:
A) 600	B) 300	C) 350	D) 400	E) 550

Rationale: let d = total distance traci traveled 1 / 3 = d / 3 i . e . remaining distance = 2 d / 3 she traveled 1 / 4 th of 2 d / 3 = d / 6 thus : d = ( d / 3 ) + ( d / 6 ) + 300 d = 600 answer : a
Answer: A
