Using proportions, it is found that it takes 6 hours to water the entire lawn.
- This question is solved by proportions, using a rule of three.
- The sprinkler waters [tex]\frac{1}{12}[/tex] of the lawn in [tex]\frac{1}{2}[/tex] of an hour. How long it takes to water the entire lawn, which is equivalent to 1?
The rule of three is:
[tex]\frac{1}{12}[/tex] lawn - [tex]\frac{1}{2}[/tex] hour
1 lawn - x hours
Applying cross multiplication:
[tex]\frac{1}{12}x = \frac{1}{2}[/tex]
[tex]2x = 12[/tex]
[tex]x = \frac{12}{2}[/tex]
[tex]x = 6[/tex]
It takes 6 hours to water the entire lawn.
