Question

The length of an object in feet is equal to three times its length in yards. The length of a waterslide is 48 feet. Write and pick equation to find the length of a waterslide in yards

Answer 1

Equation is:
`L=3y`

Length in yards is 16 yards.

Explanation:

Let 'L' represent length in feet and 'y' in yards.

Given:

Length of the waterslide is,
`L=48\ ft`

Length in feet is three time its length in yards. Therefore,

Length in feet = 3
`*` Length in yards.

∴
`L=3y`

Dividing both sides by 3, we get:

`(L)/(3)=(3y)/(3)\\\\y=(L)/(3)`

Now, plug in 48 for 'L' and solve for 'y'. This gives,

`y=(48)/(3)\\\\y=16\ yards`

Therefore, the length of the waterslide of length 48 feet in yards is 16 yards.
