Answer:
30 minutes.
Step-by-step explanation:
The more pipes you have the less time it takes to water the field.
This is inverse proportion.
t varies as 1 / p
t = k/p
Inserting the given values:
60 = k/3
so k = 180.
and the equation of variation is
t = 180 / p.
When the number of pipes = 6 the time
= t = 180 /6
= 30 minutes.
The time that should be needed is 30 minutes.
Given that,
- 3 pipes take 60 minutes to water the field.
Based on the above information, the calculation is as follows:
[tex]t = k\div p\\\\60 = k\div 3[/tex]
k = 180
Now
[tex]t = 180 \div p\\\\t = 180 \div 6[/tex]
= 30 minutes.
Therefore we can conclude that The time that should be needed is 30 minutes.
