What is the length of the second question on page 68 of the first volume of the fifth grade mathematics Yangtze River homework in 2022?
In 2022, the length of the second question on page 68 of the first volume of the fifth grade mathematics Yangtze River homework is 96 meters. According to the relevant public information, the second question on page 68 of the fifth grade mathematics Yangtze River operation in 2022 is: there is a cement lamp post every 40 meters on one side of an expressway, with 12 1. Now the cement lamppost is replaced by a new lamppost carved with 5 1 aluminum alloy. What is the distance between the two new lampposts?

1, the number of segments is equal to the number of plants minus 1, and the total length is equal to the difference between plant spacing times the number of plants minus 1. 40 times 12 1 minus 1 equals 40 times 120 equals 4800 meters.

2. The distance between two new lampposts is 4800 divided by 5 1 minus 1, which equals 4800 divided by 50 equals 96m.
