Answer 2

The answer is 8 kilometers.

Explanation:

Let X be the total cost of the taxi fare and Y be the distance traveled. If the taxi fare costs $5, $2.5 for each kilometer, we can write an inequality such as

X = 2.5 x Y.

If the total amount of money for the ride is $20, when we put it into the inequality, 20 = 2.5 x Y

Y = 20 / 2.5 = 8.

For $20 you can ride for a maximum distance of 8 kilometers.

I hope this answer helps.
