Last Chegg Expert got this wrong, please only answer if you know. Thank you!

a) For the existing layout, the cumulative "load distance" or "movement cost" = feet (enter your response as a whole number). Based on the flows shown in the matrix, one should expect that the centers A and will be next to each other as they have the highest number of moves betwer Based on the flows shown in the matrix, one should expect that centers C and will be next to each other as they have the second highest number of moves betwe other. b) The aim is to improve the layout so that the total "movement cost" can be reduced. Functional locations for A and D have been fixed. In the improved layout, the work center that should be located between them is: Tailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwind shoe, which sells for $210, contains both gas- and liquid-filled compartments to provide more stability and better protection against knee, foot, and back injuries. Manufacturing the shoes requires 10 separate tasks. There are 400 minutes available for manufacturing the shoes in the plant each day. Daily demand is 62. The information for the tasks is as follows: a-b) The correct precedence relationship with one of the possible assignments of tasks using the "ranked positioned weight" to workstations is shown in c) The efficiency of the assembly line with 5 workstations shown in the figure chosen above= % (enter your response as a percentage rounded to one decimal place). d) The idle time for the assembly line per cycle = minute(s) (enter your response as a whole number)
