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.
Let,
x be the total distance.
60% of x = 30

Dividing both sides by 0.6

The full road trip is 50 miles.

Divide both sides by 5 , so 5(x + 5)/5 < 85/5 , which will give you <span>x + 5 < 17 , then minus 5 from both sides which will give you x < 12 . hope this helps !</span>
