Zack spent the weekend in the Twin Cities with friends. Now it is time to drive home. His friend says, “Zack, the back tire on the driver’s side of your car is low. Let’s look at it.”
They look at the tire. It is too low to be driven home. Zack needs to replace the low tire with the spare tire or put more air in the low tire. He opens the trunk. He sees the spare tire, but he does not see a wrench or a jack. Zack will not be able to replace the tire.
There is a gas station three blocks away. Zack drives there. He finds the air hose and inflates the tire with the air. He’s ready to go. On his way home, Zack checks the tire pressure on his car's information panel to make sure the tire is still full.
