What is a Ratio?

A ratio shows us the number of times a number contains another number.

As the ratio is given to us 1inch:30 miles, therefore, one inch on the map will be equal to 30 miles. so using the ratio we can write,

$\rm \dfrac{Map}{Reality} = \dfrac{1\ inch}{30\ miles}\\\\\rm \dfrac{3.5\ inches}{Reality} = \dfrac{1\ inch}{30\ miles}\\\\Reality = 91.5\ miles$

Hence, the length of Gina's trip will be 91.5 miles.
