Answer:
travel within the given budget.
Let d represent the distance in kilometers.
The cost for the ride can be determined by the equation: Cost = $5 + ($2.50 * d)
To find the maximum distance within the given budget of $20, we can set up the inequality:
$20 ≥ $5 + ($2.50 * d)
This inequality ensures that the total cost of the ride, which includes the $5 base fee and the $2.50 per kilometer charge, is less than or equal to the budget of $20.
