A new fast growing strain of yeast cells reproduces by deviding very two minutes. Thus one becomes two after two mintes, four after four minutes and eight after eight minutes. If a newly devided cell is placed in a rectangular vat 6 inches by 8 inches by12 inches, and after an hour the vat is full of yeast, how long did it take to fill half the vat.

1)15
2)24
3)30
4)48
5) none of the above

E for me. Answer should be 58 min. since in the last 2 min, the vat should have been half full. About 10 sec. to find out and 20 to read the problem

I took more than a min. Unnecessarily worked out the area of the rectangle.

Same here it took me a minute to understand.

THIS IS a classic problem that is so simple, it couldnt get any simpler, yet all those fillers and distractions could throw us off. Good job Paul
