Calculating Time for Eating a Watermelon

To calculate the time it takes for the wolf and the hare to eat the same watermelon together, we can use the information provided about their individual eating times.

Given: - Wolf eats a watermelon in 20 minutes. - Hare eats a watermelon in 30 minutes.

Calculation

To find out how long it will take for them to eat the watermelon together, we can use the formula:

Total time = (Time taken by the first animal * Time taken by the second animal) / (Time taken by the first animal + Time taken by the second animal)

Plugging in the given values: Total time = (20 * 30) / (20 + 30)

Total time = 600 / 50

Total time = 12 minutes

So, it will take the wolf and the hare 12 minutes to eat the same watermelon together.

This calculation is based on the given eating times of the wolf and the hare.
