Final answer:
After converting both measurements to feet, the Jiaozhou Bay Bridge is 13,572 feet longer than the Lake Pontchartrain Causeway.
Step-by-step explanation:
The Jiaozhou Bay Bridge in China spans 26.4 miles, and the Lake Pontchartrain Causeway in Louisiana spans 41,940 yards. To compare their lengths, we first need to convert these measurements to the same units. We know that 1 mile equals 5,280 feet, so the Jiaozhou Bay Bridge is 139,392 feet long (26.4 miles × 5,280 feet/mile). There are 3 feet in a yard, so the Lake Pontchartrain Causeway is 125,820 feet long (41,940 yards × 3 feet/yard).
To find out how much longer the Jiaozhou Bay Bridge is than the Lake Pontchartrain Causeway in feet, we subtract the length of the Causeway from the length of the Bay Bridge:
139,392 feet - 125,820 feet = 13,572 feet.
Therefore, the Jiaozhou Bay Bridge is 13,572 feet longer than the Lake Pontchartrain Causeway.
