Train Speed, Wind, and Smoke
Date: 7/2/96 at 19:40:39 From: Anonymous Subject: Train Speed, Wind, and Smoke If an electric train is climbing a hill at 45 kph and the wind is blowing at 12 knots how far is the smoke blowing back down the hill?

[Archivists note: Actually, the answer is that there IS no smoke because... it's an electric train!] -Doctor Robert, The Math Forum Check out our web site! http://mathforum.org/dr.math/
