Question

a bathtub fills at a constant rate. the amount of water in the tub increases by 1/2 gallon evert 1/10 minute. what is the unit rate at which the tub fills?

Answer 1

Do 1/2 x 1/10 which equals 10/2. 10/2 is 5 gallons if u divide 10 divided by 2. So the unit rate is 5 gallons per minute.

Answer 2

5 gallons per minute

Explanation:

A bathtub fills at a constant rate.

The amount of water in the tub increases by
`(1)/(2)` gallon every
`(1)/(10)` minute.

Unit rate: The amount of gallons fill bathtub in unit minute.

We are given rate is constant.

Therefore,

`\text{Unit rate} = \frac{\text{number of gallons}}{\text{Number of minute}}`

`\text{Unit rate} = ((1)/(2))/((1)/(10))`

`\text{Unit rate} = 5\text{ gallons per minute}`

Hence, The unit rate is 5 gallons per minute.
