Question 427535:  Two airplanes leave St. Louis at exactly the same time, but one flies due east at a rate of 350  
miles/hour and the other flies due west at a rate of 325 miles/hour. How far away from each  
other will they be after hours? Remember to use the formula , where distance  
(how far away), rate (i.e. the speed of each plane) and time (in our case, in hours).
