Question 947656: Two trains on parallel tracks start at the same point at the same time, but move in opposite directions. One train travels at 56 miles per hour (mph). At the end of 4 hours, they are 408 miles apart. Find the rate in miles per hour of the other train. (Enter an exact number.) Answer by macston(5194) (Show Source):
You can put this solution on YOUR website! The trains head in opposite directions for 4 hours, the train traveling 56 miles per hour has traveled 4 hrs(56 mph)=224 miles. Since the other train made up the remainder, it traveled 408 miles-224 miles=184 in 4 hours, or (184 miles/4hours)= 46 miles/hr ANSWER: The second train was traveling at a rate of 46 mph.
