Answer:
<h2>18mins</h2>
Step-by-step explanation:
This problem is on combined work rate
given that
Marta can vacuum the house in 30 min
then her rate= 1/30
Also, her daughter will take 45 min to vacuum the house
her daughter's rate will be = 1/45
then the combined work rate is
1/30+1/45=1/T
30+45/30*45=1/T
75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house
The answer is:
1/2 cups of flour can make 1 loaf.
1 cup would make = 1 /(1/2) = 2 loaves.
12 cups of flour would then make = 12*2 = 24
= 24 loaves.
