Problem: You are on an excursion to the beach with four of your friends. Halfway, you notice your car tyre is flat. On checking, you noticed there is a puncture on the tyre. Write an algorithm to solve the problem.

Answer 1

Initial conditions: assume that to solve the problem, we can only use a spare wheel that does not need inflation or a car service truck.

1. Recall whether you can replace the wheel or not
2. Check whether you have a spare wheel, jack, and wrenches. If yes, proceed to 3, if no, call the car service.
3. Station the jack near the punctured tire, make sure it securely fits the body or frame of the car.
4. Lift the car using your jack.
5. Untie the nuts using your wrench.
6. Remove the wheel with flat tire.
7. Mount the spare wheel.
8. Tie all the nuts with your wrench.
9. Check whether the wheel rotates freely and mounted correctly.
10. Lift your car down with the jack.
11. Remove the jack and pack it, pack your wrench, put them with the punctured wheel to the trunk.
