Question

The longest sea bridge, the Jiaozhou Bay Bridge in China, spans 26.4 miles. The longest sea bridge in the United States is the Lake Pontchartrain Causeway in Louisiana, which spans 41,940 yards. How much longer is the Jiaozhou Bay Bridge, in units of feet, than the Lake Pontchartrain Causeway

Answer 1

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.

Answer 2

2.57 yards longer

Step-by-step explanation:

Step one:

given data

We are told that the Jiaozhou Bay Bridge in China, spans 26.4 miles

Also, The longest sea bridge in the United States is the Lake Pontchartrain Causeway in Louisiana, which spans 41,940 yards

Required

Unit conversion from yards to miles

Step two:

let us convert 41,940 yards to miles

We know that 1 yard is 0.000568182 miles

hence 41,940 yards is x miles

cross multiply we have

x= 41,940*0.000568182

x=23.83 yards

Hence the difference in their lengths is

=26.4-23.83

=2.57 yards
