Answer: 2miles/ 2.5miles.
Step-by-step explanation:
If rentals for a car costs $35
subtracting this $35 from budget of $85 gives us
$85-$35= $50
By travelling one mile, we subtract $20, we're then left with
$50 - $20 = $30.
By travelling another mile, we subtract another $20, which gives
$30-$20= $10.
Since this $10 is not enough to cater for another mile, the maxmimum number of miles is 2miles.
But if allowed in halves, the $10 can cover half a mile and the longest possible distance she can travel is 2.5miles
