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
