Question 459165: The length of the rails used by a railroad is 30 feet. In years past, before railroads welded rails together, an audiable click could be heard each time the wheels of a railroad car passed over a point where rails were joined together. Old mr.neyland said that he could tell how fast a train was going by counting clicks as he looked at his pocketwatch. Approximately how long did Mr.Neyland have to count clicks for the number of clicks to equal the train's speed in miles per hour? Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! The length of the rails used by a railroad is 30 feet.
In years past, before railroads welded rails together, an audiable click could
be heard each time the wheels of a railroad car passed over a point where rails were joined together.
Old mr.neyland said that he could tell how fast a train was going by counting clicks as he looked at his pocketwatch.
Approximately how long did Mr.Neyland have to count clicks for the number of clicks to equal the train's speed in miles per hour?
: = 176 clicks in 1 mile
:
At 60 mph, a mile a minute, you would have to count 176 clicks in one minute.
60/176 * 60 ~ 20 sec
:
If you count 60 clicks in 20 sec, the speed is approx 60 mph
:
Perhaps we can we say that if you count the clicks in 20 seconds it will equal the speed in mph.
