<PRE><B>Question 50224</B>
This is a popular question on the Wonderlic. We have a comprehensive blog post on solving this problem here: http://www.beatthewonderlic.com/blog/2015/1/10/a-train-travels-20-feet-in-15-second-at-this-same-speed-how-many-feet-will-it-travel-in-three-seconds


SOLUTION:

Step 1: Get to 1.

If a train travels 20 feet in 1/5 second, then how far will it travel in 1 whole second? We mus multiply 20 by 5 to find out:

20 * 5 = 100

Step 2: Extrapolate.

If a train travels 20 feet in 1 second, then it must travel 3 times as far in 3 seconds:

100 * 3 = 300

Answer: 300 feet
