If a tumour of 1 gram doubles every 30 days, roughly how long until it reaches about 1 kilogram?

  • A.about 30 days
  • B.about 1,000 days
  • C.about 100 days
  • D.about 300 days

Answer: D

Reaching a thousand times the starting mass takes about ten doublings, since two to the tenth is 1,024, and ten periods of 30 days is 300. The last doubling alone adds half the final mass. Exponential growth means most of the mass appears in the final few doublings.
