Question

Brett can wash 2 full-length patio doors in 55 minutes. How many minutes would it take him to wash 17 full-length patio doors?

Answer 1

Brett spends 55 minutes washing 2 doors, we must find the minutes it would take to wash 17 doors.

We will first find out when it takes time to wash a door.

We will call x the time it takes to wash a door

`x=(55)/(2)=27.5`

Knowing x, we multiply the time it takes to wash one door by the 17 doors to find the minutes corresponding to washing 17 doors.

We will call y the time it takes to wash 17 doors

`\begin{gathered} y=17x \\ y=17\cdot2705 \\ y=467.5 \end{gathered}`

The answer is 467.5 minutes
