A security guard walks the equivalent of six city blocks when he makes a circuit around the building. If he walks at a pace of eight city blocks every 30 minutes, how long will it take him to complete a circuit around the building, assuming he doesn't run into any thieves?
About one-seventh of a second. But it would SEEM like it took no time at all.
That depends on the speed of the plane. Pick a suitable speed, then divide the circumference of the Earth (40,000 km) by this speed. If the speed is in km/hour, the time will be in hours.
At what speed is your ship travelling?
Going along the equator at an altitude of zero, it would take approx 19.9 hours.

With the SR-71 Blackbird being the fastest jet and having a top speed of 4100 mph, it would take roughly 6.073527548005815 hours.
The cruising speed of the Concorde was mach 2.04, or about 1552 miles per hour. Assuming that you are referring to a non-stop flight around the equator, it would take a Concorde about 16 hours to fly around the world at that speed, ignoring weather, actual range, and the rotation of the Earth.
It depends on may factor such as the speed, resistance (wind, current), and route. So there can be no precise answer
