Answer: 3 gallons
Step-by-step explanation:
From the question, we are informed that Connor is driving on a long road trip and currently has 9 gallons of gas in his car. We are also told that for every hour that he drives, his car uses up 2 gallons of gas.
After driving for 3 hours, his car would have used:
= 3 × 2 gallons
= 6 gallons of gas
Amount of gas left will be:
= 9 gallons - 6 gallons
= 3 gallons
