A road map of the state of Texas has a scale of 0.5 miles in =50 miles. If the distance between two points in the state is 600 m

tamaranim1 [39]

Answer:

6 miles

Step-by-step explanation:

Let's set up a ratio:

$\frac{0.5}{50}=\frac{x}{600}$

We can use "cross multiplication" to solve for x

Cross multiplication is multiplying the numerator of the first fraction by the denominator of the second fraction and the denominator of the first fraction by the numerator of the second fraction.

$0.5*600=50x$

$300=50x$

Divide both sides by 50 to isolate x

$x=6$
