Yurko saw a tractor slowly pulling a long pipe down the road. Yurko walked along beside the pipe in the same direction as the tractor, and counted 140 paces to get from one end to the other. He then turned around and walked back to the other end, taking only 20 paces. The tractor and Yurko kept to a uniform speed, and Yurko's paces were all 1 m long.

How long was the pipe?

Yurko walked a total of 160 meters.

In that time, he walked past the pipe twice, right?

To find the length of the pipe, we need to use the information provided in the question. Yurko counted 140 paces to get from one end of the pipe to the other when walking in the same direction as the tractor.

Since Yurko's paces are all 1 meter long, we can conclude that the total distance he walked is 140 meters (140 paces * 1 meter/pace = 140 meters).

Next, we are told that Yurko turned around and walked back to the other end, taking only 20 paces.

Since Yurko maintained a uniform speed while walking with the tractor, we can assume that the pipe did not change positions during this time. Therefore, Yurko walked the same distance in 20 paces as he did in 140 paces.

If Yurko covered a distance of 140 meters in 140 paces, then he covered a distance of 140 meters in 20 paces.

To find the length of the pipe, we can set up a proportion:

140 meters / 140 paces = X meters / 20 paces

Simplifying the proportion gives us:

1 meter / 1 pace = X meters / 20 paces

Therefore, the length of the pipe X is equal to 20 meters.

So, the pipe is 20 meters long.
