Since there are 86400 seconds and 40030 km in the earth's circumference, the plane must travel 40030/86400 km.
Assuming east-west travel at the equator.
I assume that the question is ignoring the truly minuscule relativistic effects of such a slow speed.
Also, what are the chances of having a clock on the plane which is truly in synch with its longitude? The question is poorly specified and poorly worded.
an airplane is flying at 300 m/s(672 mi/h).How much time must elapse before a clock in the airplane and one on the ground differ by 1.00 s?
