An experiment measured the evaporation rates of two liquids, liquid A and liquid B, at a certain temperature and pressure. After 2/5 hour, 5/9 cup of liquid A evaporated. After 1/3 hour, 8/9 cup of liquid B evaporated. What is the unit rate for evaporation liquid A. What is the unit rate for evaporation liquid B

Respuesta :

The unit rate for liquid A is 25/18 cups of liquid per hour. The unit rate for liquid B will be 8/3 liquid cup per hour, so liquid B evaporated faster and by 23/18 liquid faster. Hope it help!

Answer:

liquid A will evaporate at 25/18 cups per hour.

liquid B is 8/3 cups per hour.

Step-by-step explanation:

To calculate the unit rate you need to calculate per hour, remember that unit rate always uses as numerator number 1.

[tex]\frac{\frac{5}{9} }{\frac{2}{5} } \\\frac{5*5}{2*9}=\frac{25}{18}[/tex]

So the liquid A will evaporate at 25/18 cups per hour.

And the liquid B:

[tex]\frac{\frac{8}{9} }{\frac{1}{3} } \\\frac{3*8}{1*9}=\frac{24}{9}\\\frac{8}{3}[/tex]

So the evaporation rate of liquid B is 8/3 cups per hour.
