John and Steve are speed walkers in a race. John is 12 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 choice from the following answers: A) 13 seconds B) 17 seconds C) 26 seconds D) 34 seconds E) 28 seconds
Let t be the time that John spent for his final push.   Thus, per the question,   4.2t = 3.7t+12+2 ---&gt; 0.5t = 14 ---&gt; t = 28 seconds.   28 seconds is the correct answer.
