John and Steve are speed walkers in a race. John is 15 meters behind Steve when he begins his final push. John blazes to the finish at a pace of 4.2 m/s, while Steve maintains a blistering 3.7 m/s speed. If John finishes the race 2 meters ahead of Steve, how long was John’s final push?  Choose the correct option:
A) 13 seconds	B) 17 seconds	C) 26 seconds	D) 34 seconds	E) 51 seconds
Let t be the time that John spent for his final push.   Thus, per the question,   4.2t = 3.7t+15+2 ---&gt; 0.5t = 17 ---&gt; t = 34 seconds.   34 seconds is the correct answer.
