1. Understand the problem:
* You know the distance (16 feet) and the speed (4 feet per second).
* You need to find the time it takes for the rock to travel that distance.
2. Use the formula:
* Time = Distance / Speed
3. Substitute the values:
* Time = 16 feet / 4 feet/second
4. Calculate the answer:
* Time = 4 seconds
Therefore, it will take the rock 4 seconds to hit the bottom of the well.
