Respuesta :

The full road trip is 50 miles.
Step-by-step explanation:
Given,
Distance traveled by Joe's family = 30 miles
This represents 60% of the total distance to be traveled.

Answer:

20 miles away

Step-by-step explanation:

First, find the distance of the full trip:

100% * 30 miles / 60 % = 50 miles total

Then, subtract the miles they've already traveled from the total:

50 miles - 30 miles = 20 miles left
