Answer:
- 60 seconds or 1 minute.
Step-by-step explanation:We need to cut each side of 10 in cake to:- 10/2 = 5 pieces
It is possible by 4 cuts. In total the number of cuts is:- 4 + 4 = 8
Total length of the cuts is:- 8*10 = 80 in
It took 40 seconds to cut 80 in so each inch of cut takes:- 40/80 = 0.5 second
Now, total length of cuts of 12 in x 12 in cake is:- (5 + 5)*12 = 120 in
Time required to cut this cake is:- 120*0.5 = 60 seconds
