Answer:
3 miles. :-)
Step-by-step explanation:
20 - 2 = 18
18 - 3 = 15
15 ÷ 5 = 3
3 miles
you start off with 20$, minus the 2 for the entry that gives you 18$. then if you leave a $3 tip that would leave you with 15$. each mile is $5 , 5 goes into 15, 3 times , therefore you would be able to go 3 miles for $15 .
