Answer:

Louis can seal the driveway in 5.41 hours.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex]                  4 × 1x × 2.3 = 9.2x

9.2x([tex]\frac{1}{4}[/tex] + [tex]\frac{1}{x}[/tex] = [tex]\frac{1}{2.3}[/tex])

2.3x + 9.2 = 4x

9.2 = 1.7x

x= 5.411764706
