Question

один маляр может покрасить стену за 6 часов а другой за 8 часов какую часть стены они покрасят за 1 час работая вместе? ​

Answer 1

1/6+1/8=4/24+3/24=7/24

Answer 2

Calculation of Work Rate

To determine the portion of the wall that two painters can paint together in one hour, we need to calculate their combined work rate.

Let's assume that the first painter can paint the entire wall in 6 hours, and the second painter can paint the entire wall in 8 hours.

The work rate of a painter is inversely proportional to the time it takes to complete the task. Therefore, the first painter's work rate is 1/6 of the wall per hour (since he can complete the wall in 6 hours), and the second painter's work rate is 1/8 of the wall per hour (since he can complete the wall in 8 hours).

To find their combined work rate, we add their individual work rates:

1/6 + 1/8 = 4/24 + 3/24 = 7/24

Therefore, the two painters can paint 7/24 of the wall in one hour when working together.

Answer

When working together, the two painters can paint 7/24 of the wall in one hour.
