Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

Let's consider the information given:

rental price: $30 + $0.30/mile
total bill for Ken: $55.20

Let's setup an equation for the cost

set 'x' as number of miles traveled

$\hookrightarrow Cost = 30 + 0.3x$

set that equal to the total cost or bill and solve

$30 + 0.3x = 55.2\\0.3x = 25.2\\x=84$

Ken must have traveled 84 miles

Answer: 84 miles

Hope that helps!
