[Question]: A car is driving through a tunnel with many turns. After a while, the car must travel through a ring that requires a total of 4 right-hand turns. After the 1st turn, it travels 5 meters. After the 2nd turn, it travels 8 meters. After the 3rd turn, it travels a little further and at the 4th turn, it immediately exits the tunnel. If the car has driven a total of 23 meters around the ring, how far did it have to travel after the 3rd turn?
[Answer]: From the details given, the car has traveled 5 meters at the 1st turn + 8 meters after the 2nd turn + 0 meters after the 4th turn = 13 meters around the ring. It must therefore have driven 23 total meters – 13 calculated meters = 10 meters after the 3rd turn.
So the answer is 10.

[Question]: The county fair was hosting a pumpkin contest to see who could grow the biggest pumpkin in pounds. Brad entered his pumpkin with a weight of 54 pounds. Jessica's was half the weight of Brad's. Betty's pumpkin weight 4 times the amount of Jessica's pumpkin. What is the difference between the heaviest and lightest pumpkin in pounds?
[Answer]: Jessica's pumpkin weighs half the weight of Brad's 54 - pound pumpkin so 54 / 2 = 27 pounds. Betty's pumpkin weighs 4 times the amount of Jessica's 27 - pound pumpkin so it weighs 4 * 27 = 108. Betty has the heaviest pumpkin at 108 pounds while Jessica's is the lowest at 27 pounds so the difference is 108 - 27 = 81 pounds.
So the answer is 81.

The number of truck stamps is 11 + 9 = 20. The number of rose stamps is 20 − 13 = 7. Bella bought 11 + 20 + 7 = 38 stamps in all.
So the answer is 38.
