Longitude is a geographical coordinate used to specify the east - west position of a point on the Earth's surface. The first sentence correctly mentions its use in flight calculations for distance between cities. The fourth sentence correctly states that two cities can be at the same longitude. The fifth sentence is also correct as lines of longitude cross at the equator and merge at the poles.

Answer:

1. Flight calculators use latitude and longitude to find distance between cities.
2. The two cities are located at the same longitude just below the equator.
3. Lines of longitude cross at the equator and merge at both poles.
