The following diagram demonstrates all the paths through this circuit and their delays. Remember an AND gate  is a NAND gate plus an inverter (and an OR gate is a NOR gate plus an inverter). Consequently, all AND and OR  gates suffer two delay units. The longest path is from B via G1, G3, G6, G8 and is 7 delays or 7 × 0.4 = 2.8 ns.  ...
