percent ---------------- quantity
Acid type I 60.00% ---------------- x liters
acid type II 30.00% ------ 60 - x liters
Mixture 40.00% ---------------- 60
Total 60 liters
60.00% x + 30.00% ( 60 - x ) = 40.00% * 60
60 x + 30 ( 60 - x ) = 2400

A 2 liter bottle is filled completely with water from a faucet in 10 seconds. How much water was filled into the bottle each sec

telo118 [61]

Answer:

A 0.2 L water was filled into the bottle from faucet each seconds.

Step-by-step explanation:

Unit rate is defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 6 miles per hour, they are called unit rates.

Given the statement: A 2 liter bottle is filled completely with water from a faucet in 10 seconds.

⇒ In 10 sec a 2L bottle is completely filled with water from a faucet.

Unit rate per second = $\frac{2}{10} = \frac{1}{5} = 0.2 L$

Therefore, 0.2 L water was filled into the bottle each seconds.
