Calculating the Time for the Fox to Catch the Hare

To calculate the time it takes for the fox to catch the hare, we can use the formula:

time = distance / relative speed

Where: - distance = distance between the fox and the hare - relative speed = speed of the fox - speed of the hare

Given: - Speed of the fox = 18 m/s - Speed of the hare = 15 m/s - Distance between them = 30 meters

We can calculate the relative speed and then use it to find the time it takes for the fox to catch the hare.

Calculating Relative Speed

The relative speed of the fox and the hare can be calculated as follows: Relative speed = Speed of the fox - Speed of the hare

Relative speed = 18 m/s - 15 m/s = 3 m/s

Calculating Time

Now, we can use the relative speed and the distance between the fox and the hare to calculate the time it takes for the fox to catch the hare: Time = Distance / Relative speed

Time = 30 m / 3 m/s = 10 seconds

So, if everything goes well for the fox, it will catch the hare in 10 seconds.
