Question

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

Answer 1

Answer:

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

Step-by-step 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  $\frac{miles}{hours}$ .

$\frac{720}{6}$

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

$\frac{x}{4}$

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

$\frac{720}{6}=\frac{x}{4}$

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

$720 \cdot 4 = 2880\\\\2880\div 6 = 480$

So the plane flew 480 miles in 4 hours.

Hope this helped!
