Two trains leave the station at the same time, one heading west and the other east. The westbound train travels 12 miles per hou
r faster than the eastbound train. If the two trains are 360 miles apart after 2 hours, what is the rate of the westbound train? Do not do any rounding
Let x be the speed of the Westbound. Then x - 12 is speed of Eastbound. Separation speed id x + x -12 = 2x - 12 360 = 4x - 24 4x = 384 x = 96 The answer is 96 mph.
We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.
