Answer:
w = 1.25
t
The constant 1.25 denotes the rate of water flowing in the tub per minute.
Explanation:
Water is running into a bathtub at a constant rate.
In 2 minutes , 2.5 gallons of water is filled in the tub. We are supposed to find the relation between the amount of water and the time taken and we also have to find the definition of the constant of proportionality.
Let w be the amount of water and t be the time taken in minutes.
The rate at which water is filled in the tub =
= 1.25 gallons/minute
The water filled , w = 1.25
t
The constant 1.25 denotes the rate of water flowing in the tub per minute.
