Question

It takes Audrey 3/5 hour to paint 2/5

square yards of wood to be used for making shelves.

How many square yards can she paint in 1 hour?

Answer 1

If she uses 3/5 hour to paint 2/5 square yards, how many square yards can she paint in 1 hour?
If 3/5 hr=2/5 square yards
1 hr=?
1/(3/5)*2/5 square yards=2/3 square yards
Therefore she can paint 2/3 square yards in 1 hour.

Answer 2

`(2)/(3)` square yards

Explanation:

We are given that

Audrey paint area of woods in
`(3)/(5)` hours=
`(2)/(5)` square yards

We have to find the how many square of yards she can paint in 1 hour.

By unitary method

Audrey can paint area of woods in
`(3)/(5) hours=[tex](2)/(5)`square yards

Audrey can paint area of wood in 1 hour=
`((2)/(5))/((3)/(5))`

Audrey can paint area of wood in 1 hour=
`(2)/(5)* (5)/(3)=(2)/(3)` square yards

Hence, Audrey can paint
`(2)/(3)` square yards in 1 hour.
