Q. A river flows at a speed vr = 4.17 km/hr with respect to the shoreline. a boat needs to go perpendicular to the shoreline to reach a pier on the rivers other side. to do so the boat heads upstream at an angle theta = 30 from the direction to the boats pier. find the ratio of vb to vr, where vr is defined above and vb is the boats speed with respect to the water.
