In a situation in which You land your inflatable boat on a sandbar at high tide in Southeast Alaska, which has a large semi-diurnal tide. You intend to be away from the boat for 12 hours but come back early after only 8 hours. Your boat is, unfortunately, 400m from shore.
You will have to wait B) 4 hours and 25 minutes
to be able to use your boat
Explanation:
The reason behind this is that the water movement makes objects floating in its surface move at a certain rhythm. Generally, this measure is variable but after having the data of 400 m movement in 8 hours. We just have to divide to find out the speed at which the water moves the objects on its surface. We divide 400 between the 8 hours to obtain. 50 meters of distance advance in a single hour. Therefore in 4 hours and 25 minutes, it will be at the correct distance to be reached out and used.

A common crescent-shaped dune with horns pointed downwind is called a barchan dune.
A barchan or barkhan dune is a crescent-shaped dune. Barchan ("BAR-kahn") dunes form in areas with only one wind direction, and little or no vegetation. If conditions were "perfect"—the landscape was flat, winds blew from only one direction, vegetation could not grow, and sand was available but limited —barchan dunes would dominate a sandscape. One of the commonest types of dunes, it occurs in sandy deserts all over the world. Barchans are mostly formed by the wind from one direction and appear convex. They are arc-shaped, significantly asymmetrical in cross-section, with a gradual slope towards the wind sand ridge, and made out of well-sorted sand.
