Together they cleaned the pool in 3 hours, 25 minutes, and 43 seconds.
We have given,
1 pool cleaned = 8 hour
x = 1 hour
x = (1 pool cleaned * 1 hour) ÷ 8 hour = 1/8 portion cleaned.
2) we calculate the portion of the pool cleaned by Chao in an hour.
1 pool cleaned= hour
x = 1 hour
x = (1 pool cleaned * 1 hour) / 6 hour = 1/6 portion cleaned.
3) we can suggest this equation:
x = number of hour
[tex]x(\frac{1}8} +\frac{1}{6} )=1[/tex]
(number of hours) x (a portion of pool cleaned by Anita in an hour + portion of pool cleaned by Chao in an hour) = 1 pool cleaned.
4) we solve this equation:
[tex]x(\frac{1}{8} + \frac{1}{6} )=1[/tex]
least common multiple (8,6) = 24
[tex]x(7/24)=1[/tex]
[tex]x=(1*24)/7[/tex]
x = 24 / 7 ≈ 3.43 (3 hours, 25 minutes, 43 seconds)
