X and Y run a 300m race,where X beats Y by 30m. To do a favor to Y, X starts 30m behind the starting line in a second 100m race. Both run at the same previous speed. Which of the following is true?	Pick one:
A) X Beats Y by 2m	B) X Beats Y by 0.5 m	C) X Beats Y by 4 m	D) Y Beats X by 10m	E) X Beats Y by 3 m
Let's suppose that the speed of X is 30m/s and that the speed of Y is 27m/s.   So, in the first race, the results are the following:   X crosses the finish line in 10s. In other words, X has run 300m in 10 s.   In 10s, Y has run 270 meters.   Therefore, there is the difference of 30 meters mentioned in the question.   Now, let's review the second race.   In 11 seconds, X can complete the 300 meters race. We have to remember that X is 30 meters behind the starting line.   But in 11 seconds, Y has covered (270+27)=

297 meters. Also, it is important to notice that in 11 seconds Y cannot arrive to the finish line.   So, 300 - 297= 3 meter   Answer: X Beats Y by 3 m
<result>E</result>
