5+2.5x≤ 20

Explanation:

Answer 2

The maximum distance can be 6 kilometers.

Explanation:

You have $20 to spend on taxi fare. The ride cost $5 + $2.50 per kilometer.

Let the distance that can be covered in $20 be D

So, equation becomes:

`5+2.50D \leq 20`

`2.50D \leq 20-5`

`2.50D \leq 15`

`D \leq 6`

Hence, the maximum distance can be 6 kilometers.
