Answer 2

Calculation of Snow Removal Time:

To determine the portion of snow that will remain uncleared in the yard, we need to calculate the total time taken by both Aydar and Marat to clear the snow when they work together.

Given: - Aydar takes 20 minutes to clear the snow. - Marat takes 25 minutes to clear the snow. - Aydar and Marat work together for 10 minutes.

To calculate the time taken by Aydar and Marat together, we can use the formula:

1 / (1/Aydar's time + 1/Marat's time)

Let's calculate the time taken by Aydar and Marat together:

1 / (1/20 + 1/25) = 1 / (0.05 + 0.04) = 1 / 0.09 = 11.11 minutes

Therefore, when Aydar and Marat work together, they can clear the snow in approximately 11.11 minutes.

Calculation of Remaining Snow:

To calculate the portion of snow that will remain uncleared, we need to subtract the time taken by Aydar and Marat together from the total time taken by Aydar alone.

Total time taken by Aydar alone = 20 minutes Time taken by Aydar and Marat together = 11.11 minutes

Remaining time = Total time taken by Aydar alone - Time taken by Aydar and Marat together

Remaining time = 20 minutes - 11.11 minutes = 8.89 minutes

Therefore, if Aydar and Marat work together for 10 minutes, approximately 8.89 minutes worth of snow will remain uncleared in the yard.

Please note that the above calculations are based on the given information and assumptions.
