Question 659529: A northbound train and a southbound train meet each other on parallel tracks heading in opposite directions. The northbound train travels 16 miles per hour faster than the southbound train. After 2 hours, they are 268 miles apart. At what speeds are the two trains traveling?

You can put this solution on YOUR website!
They are moving apart at the sum of their speeds
Call the speed of the southbound train +s+
+s+%2B+16+ is the speed of the northbound train
-------------
+268+=+%28+s+%2B+s+%2B+16+%29%2A2+
+268+=+4s+%2B+32+
+4s+=+268+-+32+
+4s+=+236+
+s+=+59+
+s+%2B+16+=+75+
The southbound train's speed is 59 mi/hr
The northbound train's speed is 75 mi/hr
