Junior high school mathematics, the road team is built in two days 180 km, and in four days it is built in 288 km. How much did it cost in eight days? brick by brick
There is something wrong with this topic. If it is understood as 180 km, it can be repaired in two days and 288 km in four days, that is, it can be repaired several times every two days.

288-180 =108km

In this way,180km can be completed in two days.

It can be repaired in 4 days 180+ 108 = 288km.

288+ 108=396 km can be repaired in 6 days.

396+ 108=504 km can be repaired in 8 days.

10 day can repair 504+108 = 612km.

Calculated in arithmetic progression.

This engineering team is getting more and more boring.
