Answer:

Total number of kilometers in the ride = 5 km

Number of kilometers Garret has already biked = k km

Number of kilometers Garret left to ride = 5 - k km

Number of minutes Garret takes per kilometer = 4 minutes.

Step-by-step explanation:

1. It takes 4 minutes for Garret to go a kilometer. Then

Number of minutes Garret takes per kilometer = 4 minutes.

2. Suppose the variable $k$ is the number of kilometers Garret has already biked.

3. Garret is partway through a 20-minute bike ride. It takes 4 minutes for him to go a kilometer. Then

Total number of kilometers in the ride is

$20\div 4=5\ km$

4. Suppose the variable $k$ is the number of kilometers Garret has already biked. Then $5-k$ km is the number of kilometers Garret left to ride.

We know the Kareem spent 8 less than Marco and that Kareem spent more than 15. If we add 8 onto the 15, we know that Marco has to be more than 23.

To graph this, draw an open circle at 23 and have an arrow going to the right.
