Respuesta :
As per the concept of proportionality, the best relationship between time and water pump is y = 55.5x
Proportionality:
If two object are proportional to each other, the link between them can be described by
y = kx,
where âkâ is the constant ratio of y-values to corresponding x-values.
Given,
The water pump for a swimming pool can move 166.5 gallons of water in 3 minutes.
Here we need to find the relationship between the water pump and the time for filling.
Let us consider x be the number of minutes and y be the amount of water follows on the pump that s measured in gallons.
AS per the proportionality, the relationship is written as,
y = kx
Where k is the constant, that refers the amount of water flows in one minute.
To calculate this we have to divide the amount of water by the minutes,
Thus, equals,
=> 166.5/3
=> 55.5
Therefore, the value of k is 55.5.
Then the relationship is
y = 55.5x
