Question

Jermey and Ahmed are painting a wall. Working alone, Jeremy can paint 1/4 of the wall in 1 hour. Working together, Jeremy and Ahmed can paint the entire wall in 80 minutes. How long would it take Ahmed to paint the entire wall by himself?

Answer 1

The time taken by Ahmed to paint the entire wall by himself is 120 minutes.

Given that,

• Jermey and Ahmed are painting a wall. Working alone, Jeremy can paint one-fourth of the wall in 1 hour.
• Working together, Jeremy and Ahmed can paint the entire wall in 80 minutes.
• Here we assume the x for time taken by Ahmed.

Based on the above information, the calculation is as follows:

$\frac{1}{240} + \frac{1}{x} = \frac{1}{80} \\\\ \frac{1}{x} = \frac{1}{80} - \frac{1}{240} \\\\ \frac{1}{x}= \frac{3-1}{240} \\\\ \frac{1}{x}=\frac{2}{240}$

x = 120 minutes.

Therefore we can conclude that The time taken by Ahmed to paint the entire wall by himself is 120 minutes.
