Robots Robert and Hubert assemble and disassemble coffee grinders. Each of them assembles a grinder four times faster than they disassemble one. When they arrived at the workshop in the morning, several grinders were already assembled.

At 7:00 AM, Hubert started assembling and Robert started disassembling. Exactly at 12:00 PM, Hubert finished assembling a grinder and Robert finished disassembling another one. In total, 70 grinders were added during this shift.

At 1:00 PM, Robert started assembling and Hubert started disassembling. Exactly at 10:00 PM, Robert finished assembling the last grinder and Hubert finished disassembling another one. In total, 36 grinders were added during this shift.

How long would it take for Robert and Hubert to assemble 360 grinders if both of them worked together assembling?
