Question

On Monday, Sarah worked for 450 minutes. On Tuesday, she worked half the number of minutes she worked on Monday. On Wednesday, she worked 300 minutes. How many more minutes did she work on Wednesday than Tuesday?

Answer 1

75 minutes

Step-by-step explanation:

The minutes worked by Sarah on Monday = 450 minutes

On Tuesday, she worked half the number of minutes she worked on Monday.

`\text{The minutes worked on Tuesday = }\frac{\text{450}}{2}=225\text{ minutes}`

Thus, the number of minutes more she worked on Wednesday than Tuesday is:

`\begin{gathered} \text{Minutes on Wednesday}-\text{Minutes on Tuesday}=300-225 \\ =75\text{ minutes} \end{gathered}`

Sarah worked 75 minutes more on Wednesday than Tuesday.
