Calculation of Time for the Dog to Catch the Cat

To calculate the time it takes for the dog to catch the cat, we can use the formula:

Time = Distance / Speed

Given that the distance between the dog and the cat is 30 meters, the speed of the dog is 10 m/s, and the speed of the cat is 7 m/s, we can substitute these values into the formula to find the time it takes for the dog to catch the cat.

Time = 30 meters / (10 m/s - 7 m/s)

Simplifying the equation:

Time = 30 meters / 3 m/s

Therefore, the time it takes for the dog to catch the cat is 10 seconds.

Please note that this calculation assumes a constant speed for both the dog and the cat throughout the chase. Additionally, real-life scenarios may involve various factors that can affect the outcome, such as changes in speed, agility, and other environmental factors.
