Rita is in her way home in her car. She has driven 30 miles so far, which is three-fifths of the way home. What is the total length of her drive?

If Rita has driven 30 miles so far (three-fifths of the way home), you can calculate what is the total length of her drive using the following steps:

x ... total length

three-fifths of the way home = 30 miles

3/5 of x = 30 miles

3/5 * x = 30 / * 5/3

x = 30 * 5/3

x = 50 miles

The total length of her drive is 50 miles.
