A magic slug is sitting on a platypus. The slug doubles in weight each hour. If the slug weighs 1 pound at noon, at what time will the slug weigh 128 pounds?

Answer :

The magic slug will weigh 128 pounds at 7 PM.

To determine what time the magic slug will weigh 128 pounds, we need to understand exponential growth since the slug doubles in weight each hour.

The slug weighs 1 pound at noon. Each hour, the weight doubles, so we can calculate the weight at each hour as follows:

  1. 1 PM: 2 pounds
  2. 2 PM: 4 pounds
  3. 3 PM: 8 pounds
  4. 4 PM: 16 pounds
  5. 5 PM: 32 pounds
  6. 6 PM: 64 pounds
  7. 7 PM: 128 pounds

From this calculation, we see that the slug reaches 128 pounds at 7 PM.
