Answer: The passenger will travel 17 miles.
Step-by-step explanation:
Since we have given that
Cost of a taxicab ride = $2.50
Cost of per mile = $1.10
Total cost of the trip = $21.20
Let number of miles the passenger travel be x
According to equation,
[tex]2.50+1.10x=\$21.20\\\\1.10x=\$21.20-\$2.50\\\\1.1x=18.7\\\\x=\frac{18.7}{1.1}\\\\x=17\ miles[/tex]
Hence, the passenger will travel 17 miles.
