Problem of the Week

1) Randy's science project was making a rain gauge to measure the amount of rain for one week. It rained each day that week, starting on Monday, and each day the amount of rain in the gauge doubled. By the following Sunday, the rain gauge was completely filled. On which day was the rain gauge half-filled?

2)Three clocks in the train station give the following readings:

CLOCK A: 8:00 CLOCK B: 8:50 CLOCK C: 8:20

One clock is 20 minutes fast. One clock is slow. One clock is off by half an hour.

Help the passengers figure out what time it really is.
