Problem Analysis

We are given the following information: - Cinderella needs to be home by 12:00. - At 11:45, she has already covered half of the distance. - If she does not change her speed, she will be home by 11:55.

We need to find the speed at which Cinderella is traveling.

Solution

Let's assume that Cinderella's total distance from her current location to her home is represented by d. We know that at 11:45, she has already covered half of the distance, which is d/2.

We can calculate the time it takes for Cinderella to cover the remaining distance as follows: - From 11:45 to 12:00, there are 15 minutes. - If she arrives home at 11:55, she will have taken 10 minutes to cover the remaining distance.

Using the formula speed = distance / time, we can calculate the speed at which Cinderella is traveling: - Speed = (d - d/2) / 10

Simplifying the equation: - Speed = (d/2) / 10 - Speed = d / 20

Therefore, the speed at which Cinderella is traveling is d / 20.

Answer

The speed at which Cinderella is traveling is d / 20.
