A snail finds itself at the bottom of a well. The well is 1530 centimeters deep. Each day the snail struggles up 180 centimeters and then stops to rest. While it is resting the snail slides down 30 centimeters. How long before it reaches the top of the well?

Answer 1

Approximately 10.2 days. Just subtract the amount it slides from the amount it ascends, and divide into 1530.
