Imagine that radar had never been invented and that we instead had to rely on a less reliable method of measuring distances in our solar system. if that method led us to underestimate the earth-sun distance by 10%, how would it affect other measurements in the distance chain?

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
