The scores she did record were 92, 84, 86, and 94. What score did she earn on each of the two tests if her average score for the period is 90? A. 91
B.90.5
C. 92
D. 91.5

If the ship travels 30° north of west, then the ship moves to the north a certain distance, and to the west a certain distance.

north: 30 miles X sin(30) = 15 miles

west: 30 miles X cos(30) = 26 miles

The distance north is 15 miles.

The total distance west is 226 miles.

We can use the Pythagorean theorem to find the distance from the point where the ship began.

distance = sqrt(15^2+226^2)

distance = sqrt(51301)

distance = 226.5 miles

The distance from the starting point is 226.5 miles.
