Unless you are a sprinter or are doing ultra-short race pace training, the answer is swim faster in practice and more often than you do now. You also seem to explore newer and better techniques as to how research experts seem to solve equations and problems. speed up. B: This answer choice incorrectly uses "When viewed from the window of a speeding train" to modify "the speed", illogically implying that the speed of nearby Explore Target Test Prep's MASSIVE 110-point score improvement guarantee. An hour later, a train moving 80 mph leaves heading the same direction on a parallel track. AND use S = D/T to find distance or time (using vs for S). PDF Name: Date: Class: Get in Gear Worksheet Answer Key The speed of the express train is 12 miles per hour faster than the speed of the local train. Tags: Question 14 .
