Best Answer

Speed = distance ÷ time

→ time = distance ÷ speed = 1920 miles ÷ 640 miles/hour = 1920 ÷ 640 hours = 3 hours.

How is the air moving below an airplane wing different from the air moving above it?

As an airplane flies, a strong "wind" blows across the wing (an object moving through still air works the same way as a strong wind blowing across a still object). An airplane wing is bent so that there's more curvature on top than on the bottom. For air to get to the back of the wing, it has a longer distance to travel than if it flows along the bottom of the wing. Since there is less distance below, air doesn't travel as quickly to get to the back of the wing as it does in a path across the top, so air moves more slowly underneath.
