Q:

3 pipes take 60 minutes to water the field. How much time will it take to water the field with 6 pipes? Is this direct proportion or inverse proportion and why? Full working out and equation please.​

Accepted Solution

A:
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 / pt = k/pInserting the given values:60 = k/3so k = 180.and the equation of variation ist = 180 / p.When the number of pipes = 6 the time= t = 180 /6= 30 minutes.
