ripple carry adder
Half Adder is implemented with XOR and AND gate. A. FA is implemented with 2 HA and 1 OR gate The propagation delay of XOR -gate is twice that of AND / OR gate. Propagation delay of AND/OR is 1.2 ms. A 4-bit ripple carry binary adder is implemented using 4 full adder. the total propagation time of this 4 bit binary adder in micro second is ________?

Ripple carry adder
Refer : https://gateoverflow.in/8250/gate2015-2-48 Here i dont understood how they calculated 12ns . I got that the first full adder will take 4.8ns time at that 4.8 ns we'll get the carry as well as the sum, in that duration the first XOR Ai ... for subsequent operands but for final sum the carry first need to be propagated through all full adder first Why 4.8 + 3*2.4 ??
