Train Speed, Wind, and SmokeDate: 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? Date: 7/2/96 at 22:1:32 From: Doctor Robert Subject: Re: Train Speed, Wind, and Smoke This question cannot be answered unless we know the direction of the train's motion and the direction of the wind. [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/ |
