Question

A plane flew 720 miles in 6 hours. How many miles did the plane fly in 4 hours?

Answer 1

`\huge\boxed{\texttt{480 miles}}`

Explanation:

We can create a ratio here to find the constant of proportionality and use that to find how many miles the plane flew in 4 hours.

We know the plane flew 720 miles in 6 hours. We can create a ratio, represented as a fraction, in the form
`(miles)/(hours)` .

`(720)/(6)`

We can now make another ratio where we use a variable for the miles flown in 4 hours.

`(x)/(4)`

Since the ratios are equal, we can create an equation.

`(720)/(6)=(x)/(4)`

To find the value of x, let's cross multiply.

`720 \cdot 4 = 2880\\\\2880/ 6 = 480`

So the plane flew 480 miles in 4 hours.

Hope this helped!
