Question

Norma prepared 10.65 kilograms of dough after working 6 hours. How many hours did Norma work if she prepared 14.2 kilograms of dough? Assume the relationship is directly proportional.

Answer 1

8 hours

Explanation:

Since the relationship is directly proportional, we can make the following proportion, taking into account the data given in the statement:

`(6)/(10.65)=(x)/(14.2)`

We solve for x:

`\begin{gathered} x=(6\cdot14.2)/(10.65) \\ x=8\text{ hours} \end{gathered}`

Therefore, the number of hours would be 8 hours
