### Question

A beef cow gained 75 kg over a period of two months and two days. What is its average weight gain?

### Options

The correct answer is C.

### Explanation:

In this question, we are given the information that a beef cow gained 75 kg over a period of two months and two days. We are asked to find the average weight gain of the cow.

To find the average weight gain, we need to divide the total weight gain by the number of months and days. In this case, the total weight gain is 75 kg, and the period of time is two months and two days.

To convert the two months and two days into a single value that we can use for our calculation, we need to convert the two days into a fraction of a month. Since there are approximately 30 days in a month, we can calculate the fraction as follows:

\( \frac{2}{30} \) = 0.067 Now, we add this fraction to the two months to get the total time in months: 2 + 0.067 = 2.067 Next, we divide the total weight gain of 75 kg by the total time in months of 2.067: \( \frac{75}{2.067} \) = 36.285 Therefore, the average weight gain of the beef cow is approximately 36.285 kg. Looking at the options given, we can see that Option C: 1.28 kg is the closest to our calculated average weight gain of 36.285 kg. So, the correct answer is Option C: 1.28 kg. It's important to note that the options provided in the question might not be the best choices, as they are quite different from the calculated average weight gain. In real-life situations, the average weight gain of a beef cow over a specific period may vary depending on various factors such as breed, diet, and management practices.
