Question

Uche pumps gasoline at a rate of 18 L/min

What is Uche's pumping rate in mL/s ?

Answer 1

there are 1000 mL in a Liter and 60 seconds in a minute

18 L / min = 18,000 mL /min

so in mL/s the answer is 18000 / 60 = 300 mL/s Answer

Answer 2

`\frac{300\text{ ml}}{\text{ second}}`

Explanation:

We have been given that Uche pumps gasoline at a rate of 18 L/min. We are asked to find Uche's pumping rate in mL/s.

To solve our given problem we need to convert our given rates.

1 liter = 1000 ml

1 minute = 60 seconds.

Upon

`\text{Uche's pumping rate}=\frac{\text{18 L}}{\text{min}}* \frac{\text{1000 ml}}{\text{L}}* \frac{\text{1 min}}{\text{60 seconds}}`

`\text{Uche's pumping rate}=\frac{18*\text{1000 ml}}{\text{60 seconds}}`

`\text{Uche's pumping rate}=\frac{18,000\text{ ml}}{\text{60 seconds}}`

`\text{Uche's pumping rate}=\frac{300\text{ ml}}{\text{ second}}`

Therefore, Uche's pumping rate in mL/s would be
`\frac{300\text{ ml}}{\text{ second}}`.
