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

75/1350= 1/T
1/18=1/T
This means that they will both take 18 minutes working together to vacum a house
