anyway,
= 3 hours if they both clean the house
Step-by-step explanation:
p= number of people cleaning the house
h= hours/time spent
since its inverse proportion, if one value increases, the other one decreases. if its direct, if one value decreases/increases, rhe other value also increases/decreases. in this case value a (p) increases so value b (h) will decrease.
equation: p=k/h
1p (Sandra)=6 hours
2p (Sandra & Eya) =3 hours
6h/2p= 3h
